ABSTRACT:
Conventional integrable differential amplifiers have implanted resistors as load resistors, the limited size of which represents a barrier for the minimization of current consumption. In accordance with the present invention, the load resistors are replaced by load elements that represent non-linear two-terminal elements such as diodes, the potential at these load elements is held constant via a control loop by a controlling element such as a control transistor. This allows the current consumption of differential amplifier stages to be reduced to the order of magnitude of the residual current without increasing the area required for integration of the circuit.
