A circuit arrangement for increasing the gain-bandwidth product of a CMOS amplifier having a differential cell input stage comprises, within said input stage: a pair of active components having a characteristic function which corresponds with that of a negative value resistor, for increasing the transconductance of the stage, a pair of capacitors being each respectively associated with a corresponding one of the active components to introduce a pole/zero pair in the frequency response from the amplifier, and an additional input stage cross-connected to the differential cell for bringing the frequency value of the zero a predetermined distance away from the amplifier clipping frequency.

Abstract

A circuit arrangement for increasing the gain-bandwidth product of a CMOS amplifier having a differential cell input stage comprises, within said input stage: a pair of active components having a characteristic function which corresponds with that of a negative value resistor, for increasing the transconductance of the stage, a pair of capacitors being each respectively associated with a corresponding one of the active components to introduce a pole/zero pair in the frequency response from the amplifier, and an additional input stage cross-connected to the differential cell for bringing the frequency value of the zero a predetermined distance away from the amplifier clipping frequency.
