Differential amplifier with constant transconductance has 2 differential amplifier units with level shifters, constant current source, output currents interconnected for additional output currents

摘要

The device has two differential amplifier units (10,20), two level shifters (30,40), a current switch (50) between the amplifier units for dividing the common mode input region associated with them and a first constant current source (60). Differential amplifier unit output currents are cross-connected to form additional output currents.
