Abstract : The patent application describes a balanced input zero differential detector used for example, in radar, to determine the center of gravity of the video pulse of a return echo. A balanced tunnel diode is coupled across the input of a differential amplifier. The tunnel diode is positioned in relation to four input signals and ground such that it is biased at a stable low-current-high-voltage state. An incoming signal causes a series of state changes designed to fire the diode at zero crossing resulting in the occurrence of a step voltage which in turn causes the differential amplifier to change state.
