Abstract :
A new CMOS low-voltage linear transconductor for High Frequency (HF) applications is presented. It uses tunable floating batteries between the input and the transistor gates of each inverter that forms the transconductor. The proposed transconductor operates under constant low voltage supply and transconductance and output resistance are independently tunable. It is suitable to be used in HF continuous time filters with programmable center frequency and quality factor
