Wide Tuning Range Oscillator

View page
US Patent:
20200177126, Jun 4, 2020
Filed:
Nov 27, 2019
Appl. No.:
16/697801
Inventors:
- San Diego CA, US
Mohammad FARAZIAN - San Diego CA, US
Wu-Hsin CHEN - San Diego CA, US
Razak HOSSAIN - San Diego CA, US
International Classification:
H03B 5/12
Abstract:
Certain aspects provide a circuit for generating an oscillating signal. The circuit generally includes a voltage-controlled oscillator (VCO) having cross-coupled transistors, a first capacitive element and a second capacitive element coupled to the cross-coupled transistors, and a first inductive element and a second inductive element coupled to the cross-coupled transistors. First terminals of the first inductive element and the second inductive element are coupled to first terminals of the first capacitive element and the second capacitive element, respectively. The circuit also includes a control circuit having an output coupled to a supply voltage node at second terminals of the first inductive element and the second inductive element, and a feedback path coupled between the VCO and an input of the control circuit.

Degeneration For A Wideband Voltage-Controlled Oscillator

View page
US Patent:
20190089302, Mar 21, 2019
Filed:
Sep 15, 2017
Appl. No.:
15/706034
Inventors:
- San Diego CA, US
Mehran Mohammadi Izad - San Diego CA, US
Mohammad Farazian - San Diego CA, US
International Classification:
H03B 5/12
H03L 7/093
Abstract:
The present disclosure describes aspects of degeneration for a wideband voltage-controlled oscillator (VCO) circuit. In some aspects, the VCO circuit includes a degeneration network that includes a first inductor, a second inductor, and a capacitor. The degeneration network is connected between the a supply voltage and ground, with the capacitor connected across the differential VCO, between the sources of cross-coupled PMOS transistors and the sources of cross-coupled NMOS transistors. Control circuitry selects an inductance value of a switched inductance network to select a frequency band in which the VCO circuit operates. The control circuitry also sets a switched capacitor bank and a variable capacitor bank to tune the VCO circuit to an operating frequency within the selected frequency band. The control circuitry further tunes the degeneration network to degenerate the VCO circuit to reduce phase noise in an output signal of the VCO circuit.

Switchable Inductor Network For Wideband Circuits

View page
US Patent:
20190089304, Mar 21, 2019
Filed:
Sep 15, 2017
Appl. No.:
15/705855
Inventors:
- San Diego CA, US
Mehran Mohammadi Izad - San Diego CA, US
Mohammad Farazian - San Diego CA, US
International Classification:
H03B 5/12
H01F 21/12
H01F 27/28
Abstract:
The present disclosure describes aspects of a switchable inductor network for wideband circuits. In some aspects, the switchable inductor network provides selectable inductance. The switchable inductor network includes a first coil and a second coil that includes a first inductive segment and a second inductive segment. Connection points of the second coil connect the second coil across a portion of the first coil. The switchable inductor network also includes a switch connected between the first inductive segment and the second inductive segment of the second coil. The switch is configured to change the selectable inductance of the switchable inductor network by selectively coupling the first inductive segment to the second inductive segment of the second coil in response to a control signal.

Mohammad FARAZIAN - San Diego CA, US
Gurkanwal Singh SAHOTA - San Diego CA, US
Assignee:
QUALCOMM INCORPORATED - San Diego CA
International Classification:
H04B 1/04
H04B 17/00
US Classification:
375297
Abstract:
Exemplary embodiments are related to digital pre-distortion in envelope tracking systems. A device may include an amplitude modulation-to-phase modulation (AM-PM) distortion unit configured to generate an AM-PM distortion component in response to receipt of phase data of an input transmit signal. The device may also include a local oscillator (LO) path coupled to the distortion unit and configured to convey a local oscillator (LO) signal that varies based on the AM-PM distortion component.
