Abstract
This paper presents a new high speed current mirror with continuous gain adjustment. Based on this current mirror, a variable gain current amplifier is designed in 0.18µm CMOS technology. The current gain of the amplifier can be continuously varied from 0dB to 20dB while the bandwidth of the circuit remains above 100MHz. The circuit consumes 0.9mW from 1.5V supply.
