Title: Walter Rosenzweig: Innovator in Circuit Design
Introduction
Walter Rosenzweig is a notable inventor based in Allentown, PA (US). He has made significant contributions to the field of circuit design, holding 2 patents that showcase his innovative approach to technology.
Latest Patents
One of his latest patents is the IGFET Bootstrap Circuit. This improved driver circuit is capable of driving a load impedance to substantially full VDD power supply voltage and maintaining that voltage indefinitely. The circuit features a load transistor, a feedback capacitor connected between the source and gate electrodes of the load transistor, and a fixed-valued resistor linked to an on-chip bias voltage generating circuit. This design allows for sufficient current to replenish charge lost from the feedback capacitor due to junction leakage currents. The circuit also enables the load transistor to be switched 'on' or 'off' by an externally applied signal.
Another significant patent is the Back Gate Bias Voltage Generator Circuit. This circuit consists of three MOS transistors with separate load elements coupled to the drain of each. A voltage clamp is connected to an output terminal, and the circuit operates based on the potential of a power supply and the substrate potential. The output terminal assumes a reference potential when both input potentials are within normal operating ranges, and it increases in magnitude if either input goes outside preselected operating ranges.
