A Flexible 200kHz-20MHz Ring Oscillator in a 40nm CMOS Technology

In this paper, we present a flexible ring oscillator IP designed for a 40nm CMOS technology, whose oscillation frequency can be chosen from 200kHz to 20MHz. It was developed using a new design approach, in which analog IPs are designed from scratch to be flexible, employing modular blocks that can be easily customized. The IP is silicon proven. It works with a supply voltage of 1.2V and features 5% frequency accuracy, occupying an area of 0.0022mm2.

Creating a Frequency Plan for a System using a PLL

How do you ensure that every part of a system receives the clock it needs—without wasting power or sacrificing performance? The answer lies in creating a well-structured frequency plan built around a PLL.
