ABSTRACT:
The clipping circuit has a voltage reference and a transconductance connected to a voltage input. The input is connected through the transconductance to an output resistor. The voltage output is taken between the output resistor and the transconductance. The voltage reference has a third current source feeding a diode connected transistor and a resistor. A second current source feeds into the resistor after the transistor. The base of the diode connected transistor is connected to the voltage input. The transconductance has a second transistor whose base is connected to the voltage input, collector sinks current from a fourth current source and emitter feeds current to a resistor. A first current source feeds current to a third transistor and to a current mirror. The base of the third transistor is connected between the fourth current source and the collector of the second transistor. The current mirror draws current from the output resistor and feeds current to between the emitter of the second transistor and its associated resistor. The transconductance creates a feed back loop such that a change in the first and second current sources creates a steady-state current drawn through the resistor that is one-half of the first current source current. The circuit produces symmetrical clipping of an input voltage signal at the voltage output.
