The following paper provides an introduction to analysis and design of a complementary cross-coupled LC-VCO as used in RF transmitter/receiver circuits. Different design parameters have been discussed along with their associated equations, to allow for basic on-paper calculations. The values of corresponding components are used in verification of the design via CAD simulation. The main goal is to synthesize a low-power low-noise design with a wide bandwidth of operation (tuning range). © 2018, Springer Nature Singapore Pte Ltd.
