Title: Mirza A Beg: Innovator in Clock Generation Technology

Introduction

Mirza A Beg is a notable inventor based in Lima, OH (US), recognized for her contributions to the field of electrical engineering. With a total of 9 patents to her name, she has made significant advancements in clock generation technology, particularly in variable speed constant frequency systems.

Latest Patents

One of her latest patents is a "Master clock generator for a parallel variable speed constant frequency." This invention includes a frequency select circuit that allows for the selection of an external or internal frequency reference signal. A phase comparator produces a phase error signal that represents the phase difference between the frequency reference signal and an output clock signal. The phase error signal is combined with a control signal to create an adjusted phase error signal, which is then integrated. A voltage control oscillator generates the output signal in response to this integrated adjusted phase error signal. Clamping circuits are also included to limit the maximum and minimum magnitudes of the integrated adjusted phase error signal, thereby controlling the output clock signal's frequency.

Another significant patent is the "Circuit and method for monitoring phase error modulation." This invention detects phase error between two signals by producing a phase error signal with a series of pulses. The widths of these pulses represent the phase error, and a polarity signal indicates the polarity of the phase error. The phase error and polarity signals are used to generate a count that represents the magnitude and polarity of the phase error for each pulse. This count is converted to an analog signal, which is compared to reference level signals to produce an output signal that indicates the acceptability of the phase error.
