Abstract
A power detector with a main transconductance stage and a Gilbert switch stage coupled to one another. Current sources are coupled between the main transconductance and the Gilbert switch stages. Each of the current sources is configured to generate a cascoded PMOS trickle current under the control of a DAC to control the effective voltage of the Gilbert switch stage. This mitigates the DC offsets resulting in enhanced sensitivity of the Gilbert switch stage. An increase in the conversion gain of a system using a Gilbert switch stage, for a given LO swing, is therefore obtained for a very small increase in DC power.
