The conventional cellular mobile device needs a tens-of-MHz main crystal oscillator (XO)
and 32.768 kHz real-time clock (RTC) XO for RF ultra-low-jitter PLLs and sleep operation …

Crystal oscillators take a long time and, more importantly, a significant amount of energy to
start-up. This article presents a self-timed energy injection technique to quickly start-up a …

Fast startup crystal oscillators (XOs) are needed in heavily duty-cycled communication
systems for implementing aggressive dynamic power management schemes. This article …

This paper introduces a switched capacitor crystal oscillator as a fully differential alternative
to the widely used single ended Pierce oscillator. The presented 40 MHz oscillator …

This paper presents a theoretical study and design of two techniques used to reduce start-up
time (TS) and energy (ES) of Pierce crystal oscillator (XO). An analytical study of precise …

An Impedance Guided Chirp Injection (IGCI) oscillator-based fast startup technique is
proposed in this work demonstrating startup time between 5 and 100 across a wide range of …

This paper presents a fast start-up crystal oscillator (XO) that reduces both start-up time and
energy via an elegantly effective muti-path feedforward| RN| boosting technique. To further …

Low power mobile and edge computing systems requires fast wakeup for pleasant end user
experience and for efficient data processing. Fast start up oscillators are needed to enable …

The start-up time (T_S) of MHz crystal oscillators (XOs) has significantly influenced the
power consumption of duty-cycled Internet-of-Things (loT) systems. The injection techniques …
