A method according to one embodiment may include providing a redundant feedback circuit. The method of this embodiment may also include coupling the redundant feedback circuit to a feedback control loop and decoupling a feedback circuit from the feedback control loop. The method of this embodiment may also include calibrating the feedback circuit. The method of this embodiment may also include recoupling the feedback circuit to the feedback control loop and decoupling the redundant feedback circuit from the feedback control loop. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.

A method for operating an electronic product having an application specific semiconductor circuit (ASIC) including in its circuitry both a linear regulator module for use with an optional external capacitance and a capless regulator module coupled to internal capacitance of the product selects a low-power sub-module or high-power sub-module of the capless regulator module for use in a power-up phase of the ASIC. Control logic of the ASIC determines if an external capacitance is present. If so, then the high-power capless sub-module is used during a power-up phase of the ASIC; if not only the low-power capless sub-module is used during the power-up phase of the ASIC. After power-up of the ASIC, the control logic may select the linear regulator module for certain times of operation and the capless regulator module for other times of operation or it may select one or the other for all times of post-power-up operation.

An electronic product includes an application specific semiconductor circuit (ASIC) including in its circuitry both a linear regulator module for use with an optional external capacitance and a capless regulator module coupled to internal capacitance of the product. The capless regulator module includes both a low-power sub-module and a high-power sub-module. Control logic of the ASIC is configured to determine if an external capacitance is present. If so, the control logic causes the high-power capless regulator sub-module to be used during a power-up phase of the ASIC; if not, only the low-power capless regulator sub-module is used during the power-up phase of the ASIC. After power-up of the ASIC, the control logic may select the linear regulator module for certain times of operation and the capless regulator module for other times of operation or it may select one or the other for all times of post-power-up operation.

In an integrated circuit, capacitively coupled interference (digital-switching or analog cross-talk) is prevented by constructing shielded coaxial conductors for the analog signals. The coaxial configuration comprises a primary conductor for the analog signal surrounded by a secondary conductor that is electrically isolated from the primary one and that is connected to a clean power bus such as GND or Vdd. The outer secondary conductor shunts the digital noise energy to the power bus, preventing it from injecting noise into the analog primary conductor. A similar coaxial configuration is provided with a bootstrap follower to reduce the effects of parasitic capacitance for high-speed and small analog signals.

A method and apparatus for a voltage reference is provided. The circuit may include one or more of the following features: cascode compensation with load balancing to increase the bandwidth of the amplifier for enhanced power supply rejection ratio; PMOS and NMOS in the input stage to expand common mode, having a high gain over voltage range; current mirror using active resistors; and a start-up circuit. The voltage reference comprises an amplifier having an output, the amplifier comprising a first amplifier stage and a second amplifier stage. The amplifier further includes a power-down circuit coupled to the second amplifier stage to float the amplifier output when a power-down signal is active. The voltage reference includes a source follower, the output of the amplifier coupled to the gate of the source follower, and a bandgap circuit for providing a bandgap voltage. The voltage reference further includes a level shifter coupled to the bandgap circuit, the level shifter for providing a second stable operating point, an output of the level shifter or an output of the bandgap circuit being coupled to the first amplifier stage as an input and a current mirror.

A disk drive storage device employs two control subsystems, one for transducer position digital control and the other to control and precisely regulate spindle motor angular velocity in accordance with a crystal reference and a speed correction made at least once each revolution. A single servo sector on a data surface provides prerecorded track centering information. Overall electromechanical operations during track following activities are synchronized by the crystal controlled disk spindle motor subsystem which locates the position in time and space of the servo sector and which also interrupts program execution of the transducer position digital control subsystem and causes it to execute a subroutine for track centerline position correction. Direct digital commutation of the brushless DC spindle motor by a programmed digital microprocessor is an aspect of the present invention.

This disclosure provides systems, methods and apparatus for providing an output voltage to be used in a display device. In one aspect, a circuit may include switches and a digital-to-analog converter (DAC). A charge recycling circuit may include a capacitive voltage divider providing voltage supplies for the switches to select from and provide to the DAC. A storage capacitor may be configured to be coupled one at a time and in parallel with individual capacitors of the capacitive voltage divider. The storage capacitor may store charge that may be reused. Additionally, a data control circuit may provide control signals for the switches and the DAC.
