Abstract:

A new differential input CMOS transconductor circuit for VHF filtering application is introduced. The new circuit has a very high frequency bandwidth, large linear differential mode input range and good common mode signal rejection capability. Using 0.35 /spl mu/m CMOS technology with 3 V power supply, the transconductor has a 0.9 V linear differential input range with a -54.6dB total harmonic distortion (THD) and more than 1 GHz - 3dB bandwidth. A 3rd order elliptic low pass g/sub m/-C filter with a cutoff frequency of 150MHz is demonstrated as an application of the new transconductor.
