A 0.5~0.7 V LC Digitally Controlled Oscillator Based on a Multi-Stage Capacitance Shrinking Technique

, 2019
This paper presents a 2.4 GHz LC digitally controlled oscillator (DCO) at near-threshold supplies (0.5~0.7 V). It was a challenge to achieve a low voltage, low power, and high resolution simultaneously. DCOs with metal oxide semiconductor (MOS) varactors

A Power-Scalable DCO for Multi-Standard GSM/WCDMA Frequency Synthesizers

, 2014
A Digitally Controlled Oscillator (DCO) whose power consumption can be reconfigured while maintaining an almost constant phase-noise figure-of-merit (FoM). This is achieved by using either a single-switch-pair or a complementary (i.e., double-switch-pair)

An HDL model of a digitally controlled oscillator for rapid digital PLL prototyping

, 2017
© 2017 IEEE. Simulating digitally-controlled oscillators (DCOs) presents a challenging trade-off between the accuracy and the speed. Simplistic DCO simulations have been pursued, but had limitations with nonideal effects. Here, an event-driven behavioral

A 5.4GHz 90-nm CMOS digitally controlled LC oscillator with 21% tuning range, 1.1MHz resolution, and 180dB FOM [Elektronisk resurs]

, 2008
A 5.4 GHz digitally controlled oscillator (DCO) has been implemented in a 90-nm CMOS process. It has three different frequency control words, coarse, medium, and fine. The coarse control bank uses MIM capacitors and differential MOS switches.
