Latest Patents
One of his latest patents is a digitally controlled delay device. This device includes at least one delay generating gate device, whose propagation delay is controlled by limiting operating current through a tail transistor that is regulated by its gate voltage. Additionally, it features a gate control voltage control means for managing the current limiting transistor gate voltage, along with a bank of digitally controlled MOSFET transistors in parallel configuration. The digital control is designed to switch the transistors to off and diode mode connection, with current feeding means to supply current through the bank of MOSFET transistors. The voltage across the bank of parallel transistors is utilized for gate source control voltage of the tail transistors.
Another significant patent involves operating a frequency synthesizer. This apparatus and method monitor a value of a first control signal associated with a fine frequency feedback loop connected to a signal generator. Based on this monitoring, a second control signal associated with a medium or coarse frequency feedback loop connected to the signal generator is adjusted. The first and second control signals are then output to control the frequency synthesizer.
