Abstract

In this paper we present design results related to integrated circuits for low power and high frequency transceiver implementations. We first consider the traditional LC voltage-controlled oscillator (VCO) and its operation. We then examine an implementation of a VCO that solves many practical problems with the traditional LC VCO implementation with the use of an automatic amplitude control (AAC) circuit. Finally, a method to extend the operating frequency of an oscillator using a wideband frequency doubler (FD) is discussed. The implemented VCO with AAC has an operating frequency of 7.2GHz, a tuning range of 410MHz, a phase noise of -108dBc/Hz@1MHz and it dissipates 4.32mW from a 1.8V supply. The implemented frequency doubler consumed 985μW from a 1V supply and had a 3dB bandwidth of 4GHz.
