Abstract :
A wideband CMOS low-distortion current-follower is proposed. The circuit is suitable for low-voltage, high-frequency and low distortion VLSI applications. The design avoids the use of current mirror(s) in the signal path in order to minimise the distortion caused by mismatched mirroring transistors. The circuit exhibits a large bandwidth, high linearity and low input resistance. Simulation results are provided
