Latest Patents

One of Raymond G. Brown's key patents is titled "Power supply noise compensation for a high frequency phase detector." This invention focuses on a phase detector circuit that compensates for unwanted variations induced in an input signal by the operation of a thresholding input circuit, such as a frequency divider. The circuit monitors the level of a supply voltage used by the input circuit to provide a supply variation signal indicative of such unwanted variations. This supply variation signal is then utilized to correct the output of the input circuit. In one embodiment, the invention compensates for noise in the output of a digital frequency divider used as an input circuit in a high frequency phase detector. A high-pass filter and amplifier detect the supply variations, and the supply variation signal is fed to a phase adjustment circuit. This circuit compensates for variations in supply voltage by adjusting the conduction threshold of a differential transistor pair. A variable impedance can be arranged to optimally attenuate the supply variation signal, thereby achieving maximum noise elimination at a given operational frequency. This invention is particularly useful wherever an input signal is compared against a threshold voltage.
