Abstract

In this thesis work, a digitally controlled oscillator (DCO) is designed and implemented in a 65nm 6-metal CMOS technology with 1.2 supply voltage, along with a differential-to-single-ended converter and auxiliary digital on-chip circuitry for testing. The main purpose is to study the DCO principles and design implications. The DCO is targeted for sensor network applications that use the 2.4GHz ISM band. The function and performance of the implemented DCO is verified in simulations. This thesis work is part of the CROPS project, and it serves as a preparatory step for the implementation of an ADPLL-based transmitter.
