Latest Patents
Erhardt holds a patent for a precise, high-speed CMOS track (sample)/hold circuit. This circuit utilizes a first circuit leg that includes four Schottky barrier diodes configured to form a Wheatstone bridge. The second leg features a single n-channel MOS transistor, an essentially constant current source with MOS transistors, a capacitor for holding the output signal, and reverse biasing circuitry with MOS transistors for selectively reverse biasing the four diodes. The design allows for an analog input signal to be applied to the cathode of the first diode and the anode of the second diode. An output signal of the same magnitude and polarity as the input signal is generated at an output terminal when current flows through the first circuit leg. The capacitor holds the generated output signal level when the current is switched to the second circuit leg, effectively isolating the capacitor from other components of the circuit.
