A voltage clamp circuit (200) which operates using a voltage controlled current source (I0) where the change of the polarity of the voltage controlled current source controls whether it is clamping or not. While clamping, the stability of the control loop uses the capacitance of the output (C1) to create and single pole roll-off of the loop gain and while not clamping, uses the capacitance (C2) of the circuit which sets the clamping voltage to produce the roll-off. The circuit operates in a linear fashion both while clamping and not clamping, which allows for a faster response when clamping is needed. |
