Several classifications exist of Nyquist-rate analog-to-digital converters. In this chapter the
converters are subdivided in parallel search, sequential search, and linear search. Each of …

An on-chip CMOS relaxation oscillator with voltage averaging feedback using a reference
proportional to supply voltage is presented. A voltage-averaging feedback (VAF) concept is …

A fully-integrated 18.5 kHz RC time-constant-based oscillator is designed in 65 nm CMOS
for sleep-mode timers in wireless sensors. A comparator offset cancellation scheme …

This paper presents the design of a low-voltage ultralow-power relaxation oscillator without
external components. The application field for this oscillator is the clock generation of low …

An NPN-based temperature sensor with digital output has been realized in a 65-nm CMOS
process. It achieves a batch-calibrated inaccuracy of (3σ) and a trimmed inaccuracy of (3σ) …

Integrated low-frequency oscillators can replace crystal oscillators as sleep-mode timers to
reduce the size and cost of wireless sensors [1]. Since the timer is one of the few …

A sub-μW, 1-cycle start-up CMOS relaxation oscillator has been developed with a
feedforward period control scheme and a digitally-controlled boost charging technique. The …

In wireless networks with a low duty cycle, the radio is operational for only a small
percentage of the time. A sleep timer is used to synchronize the data transmission and …

The design of a 1.8 GHz 3-stage current-starved ring oscillator with a process-and
temperature-compensated current source is presented. Without post-fabrication calibration …

This paper describes a 2.4 GHz Wake-up Receiver (WuRx) designed to operate with low-
accuracy (≪ 0.5%) frequency references [1], enabling crystal-less and thus low-cost …
