For the non-stop demands for a better and smarter society, the number of electronic devices
keeps increasing exponentially; and the computation power, communication data rate, smart …

The recent innovation of frequency-shifted (FS) backscatter allows for backscattering with
commodity devices, which are inherently half-duplex. However, their reliance on oscillators …

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 …

This article reports a 12-/13.56-MHz fast-and-energy-efficient startup crystal oscillator (XO)
featuring a binary-search-assisted two-step injection technique for ultralow-power duty …

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

In this paper, we introduce an all-digital phase-locked loop (ADPLL) for Bluetooth low
energy (BLE) that eliminates the need for a crystal oscillator (XO) other than a 32.768-kHz …

The increasing number of embedded, plugged-in radios around homes and offices in
everyday objects such as appliances, TVs, and smart speakers provides an excellent …

Crystal oscillators can be started up quickly by using energy injection techniques. However,
the generation of the injection waveform, as well as driving the large capacitive load formed …

The start-up time of crystal oscillators (T START) is a major bottleneck in reducing the
average power of heavily duty-cycled wireless/wireline communication systems [1]. Among …

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 …
