High linearity voltage-controlled oscillator
2009 Edition, October 1, 2009 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A linearization technique for CMOS voltage-controlled oscillators (VCOs) is presented. The linearity of the oscillator is improved by applying a feedback loop using a switched-capacitor network as a frequency-to-voltage converter (FVC). The technique is...

Linear voltage controlled oscillator
1988 Edition, Volume 37, March 1, 1988 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A description is given of a sinusoidal oscillator having a frequency of oscillation that can be controlled by a controlling voltage. The circuit gives ultralow distortion and stable output by virtue of an automatic gain control (AGC) loop. The oscillator is...

Stacking voltage-controlled oscillators: Analysis and application
2016 Edition, December 1, 2016 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The paper proposes a method to regulate the output frequency and duty cycle (phase) of ring oscillator by emulating a resistive voltage divider using purely digital means. To this end an additional master oscillator that can be clocked by an external frequency is...

SQUID voltage-controlled-oscillator
1983 Edition, Volume 19, May 1, 1983 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We have investigated the SQUID as a voltage-controlled source of microwaves. The low impedance "resistive" SQUID can be a relatively high power ( \sim n W), tunable, and monochromatic source for both on-chip and off-chip applications. Studies of the time-dependent junction phase and...

Low phase noise CMOS voltage-controlled oscillators
2007 Edition, October 1, 2007 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Design considerations and performance comparisons for several low phase noise CMOS voltage-controlled oscillator (VCO) topologies are presented including the Hartley, quadrature Colpitts, Clapp, and tuned-input tuned-output configurations. An indirect approach for...

Millimeter-Wave CMOS Voltage-Controlled Oscillators
2007 Edition, January 1, 2007 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The design of millimeter-wave CMOS voltage-controlled oscillators (VCOs) is reviewed. A low parasitic cross-coupled transistor layout is developed, and used to demonstrate a 140-GHz fundamental mode VCO in 90-nm CMOS and a 192-GHz push-push VCO in 130-nm CMOS....
