Overview

Reference oscillator is used to generate reference frequency and can work at the 1st or the 3rd harmonic of quartz resonator. Operating frequency is defined by external quartz resonator and external component values. Output peak-to-peak limitation system is used to reduce current consumption. Commutable capacitors are used to change carrier frequency that allows generating a frequency shift keying signal in a case of application in a transmitter. Output
resonant circuit is used to select the 2nd or 3rd harmonic.
The block is fabricated on iHP SiGe BiCMOS 0.25 um (SGB25V) technology.

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.
