Latest Patents

Robert T. Zeff holds a patent for a "Distortion-free limiter for a power amplifier." This invention addresses the challenge of limiting distortion in inverting amplifiers. The patent describes a comparator that generates a pulse when the signal level at the inverting input exceeds a reference voltage. This pulse charges a capacitor, which, when sufficiently charged, raises the gate voltage of a junction field-effect transistor (FET) above cutoff. Consequently, the FET shunts the input signal to reduce its level, effectively controlling distortion characteristics through a voltage divider. A bias voltage at the gate of the FET ensures it remains off when the amplifier is not clipping.
