A low voltage bulk driven downconversion mixer core

Abstract

ABSTRACT This paper describes a CMOS mixer core, operating at 1GHz, where the RF signal is input via the bulk. The advantages of a bulk driven mixer are low power supply voltages and low power consumption. Simulations have confirmed that a power supply as low as 1V can be used to power the mixer core, which drains approximately 1.6mA. Although the mixer core consumes very low power, it still provides reasonable gain as well as linearity
