Abstract :
A modified transconductance amplifier with low harmonic distortion and high current efficiency is proposed. It can be used in high-frequency applications up to 10 MHz. Each half of the transconductor differential input stage consists of a pair of transistors in saturation and linear regimes with a voltage feedback loop. Results of theoretical analysis are confirmed by SPICE simulations.
