A new 1.8V fierce-gate crystal oscillator based on the constant cell in 28nm CMOS technology for automotive radar applications

Autor: Patrick G. Crowley, Giuseppe Macera

Publikováno v: ISCAS

The majority of analog and digital integrated circuits with built in crystal oscillator use the Gated Pierce design where the oscillator is built around a single CMOS inverting gate. In most applications that require a high level of precision and sta
