Abstract
A complementary push-pull buffer includes complementary transconductance (GM) devices connected as source-followers to drive a load. Current flowing through the GM devices is split, on the source side, between constant-current source circuitry and a push signal current multiplier (e.g., a current mirror) and, on the sink side, between constant-current sink circuitry and a pull signal current multiplier. The devices used to implement the constant-current circuits and the current multipliers are sized such that the current multipliers provide low output impedance, while the current splitting provides low overall power consumption.
