Title: Innovations of Inventor Peter Murray

Introduction

Peter Murray is an accomplished inventor based in Louisville, Colorado. He holds 2 patents that showcase his expertise in digital phase detection and frequency lock technologies. His contributions have significantly impacted the fields of electronics and signal processing.

Latest Patents

Murray's latest patents include a "Phase frequency detector circuit having reduced dead band." This invention is a digital phase detector that conducts pump up and pump down control signals to a charge pump. Each of the control signals has pulses that exhibit a substantially 50/50 duty cycle characteristic when the input data signal and the feedback clock signal are nearly in phase. This output reduces, if not eliminates, inherent problems related to the turn-on delays of the charge pump while maintaining a locked condition. Additionally, the phase detector may include intelligence to detect and handle situations such as missing data pulses.

Another significant patent is the "Method and apparatus for detecting and correcting loss of frequency lock." This invention employs digital techniques to detect a programmable difference in frequencies over a programmable range. Once a loss of lock is detected, the re-lock sequence is initiated, stepping through a programmable sequence. The invention detects frequency differences by counting down two counters and evaluating the value left in one when the other reaches terminal count, using a programmable tolerance of frequency differences before declaring a loss of lock.
