Latest Patents
One of his latest patents is titled "Efficient epoch processing in multichannel global positioning system signal receiver." This invention includes a first memory, an address counter, and an adder. The first memory has KN locations that store K sums of mixer samples during an epoch interval. The mixer samples are generated at a first clock frequency from a mixer for N channels corresponding to N satellites in a GPS receiver. The address counter generates an address modulo-KN corresponding to a first location in the memory at the first clock frequency. The adder adds one of the mixer samples to the contents of the first location to generate a sum, which is then written into the first location.
Another significant patent is the "Low voltage temperature and V.sub.cc compensated RF mixer." This RF mixer utilizes frequency and bias compensation for improved performance characteristics. The RF mixer receives bias signals that are dependent on V.sub.CC levels to internally balance the local oscillation received and mix the perfectly bias balanced internally generated oscillation signal with the RF input.
