High speed PIN diode driver circuit

Abstract:

An apparatus includes a first circuit and a second circuit. The first circuit may be configured to inject charge into an I-region of a PIN diode in response to a first state of a control signal. The second circuit may be configured to remove charge from the I-region of the PIN diode in response to a second state of the control signal. A radio frequency switching time of the apparatus is generally about two orders of magnitude lower than a carrier lifetime of the PIN diode.
