Abstract
An improved voltage clamp for operating with wireless communication input circuits over the RF band. The clamp provides for symmetrical clamping for excessive positive and negative input voltage excursions. The clamp does not exact a current penalty when operating in the non-excessive positive and negative input voltage regimes. The clamp is comprised of an input node, a capacitor, a MOS transistor, a diode and a ground potential node.
