Abstract :
In this paper, a new technique for linearizing long tail differential pair (LTP) is proposed. It is shown that the proposed linearized fully differential transconductor offers excellent linearity. The proposed transconductor is used to design fully differential second order lowpass and bandpass filters suitable for VLSI. PSpice simulation results for the proposed fully differential transconductor and its filter application indicating the linearity range and verifying the analytical results are also given
