Abstract:
A variable gain amplifier (VGA) disclosed herein includes: an input voltage connector; a number of voltage to current converter circuits generating signal currents; a gain adjustment connector adapted to a current steering mechanism; current mirrors connected to each of the voltage to current converters copying the signal currents; and a steering mechanism adapted to steer the copied currents to a load resistor or to another appropriate location based on the signal present at the gain adjustment connector.
