Highly linear high-speed transconductance amplifier for Gm-C filters










Image Number 2 for United States Patent #6566949.

A transconductance amplifier and method for improving the phase response and linearity. A differential amplifier circuit receives differential signals for amplification on respective bases of input bipolar transistors. The transistors amplify a small signal received on the based connections to produce an amplified output current. The differential amplifier circuit is connected to load impedances which form a cascode transconductance amplifier output stage. Feedback transistors provide a feedback voltage from the emitters of each of the different bipolar transistors to the base, improving the linearity of the differential amplifier. Phase compensation is provided by cross coupling through first and second capacitors a portion of each individual differential signal component to the base connections of the differential amplifier input transistor.
