A complementary CMOS gain cell is proposed that provides wide-band linear amplification of bidirectional currents. The gain of the circuit is electronically variable and the cell has attractive cascading properties. An experimental circuit achieves a gain range of 1.1 to 11 with less than 1% THD and a gain-bandwidth product of 40 MHz.
