Variations Among Current-Sink/Source Circuits with a Single Op
Amp

Abstract: The design differences among five constant-current circuits are analyzed. Performance data are
discussed, and illustrate the different compromises between precision, dynamic impedance, and compliance
range for some of the circuit designs.

A controlled constant-current source or sink is a useful circuit block to use in designing electronic applications
such as sensor bias, amplifier bias, and special waveform generation. These types of circuits exhibit high-output
dynamic impedance, while delivering relatively large curre……
