Title: Innovations by Alexis Shishkoff

Introduction

Alexis Shishkoff is a notable inventor based in Raleigh, NC (US). She has made significant contributions to the field of electronics, particularly in the development of advanced signal processing technologies. With a total of 2 patents, her work has garnered attention for its innovative approaches to solving complex engineering challenges.

Latest Patents

One of her latest patents is a "Phase/frequency detector for dejitter applications." This invention includes two D-Q flip-flops, an OR gate, and an exclusive NOR (XNOR) gate. The phase/frequency detector is designed to work with a clock dejitter PLL, where the underflow and overflow flags from a FIFO are connected to the OR gate's inputs. The Q outputs of the flip-flops are linked to the XNOR gate's inputs. The recovered clock signal is connected to the first flip-flop's clock input, while the VCXO's output is linked to the second flip-flop's clock input. This design ensures that when the phase is locked, the output of the XNOR maintains a 50% duty cycle, stabilizing the VCXO output frequency.

Another significant patent is the "Method and apparatus for correcting imperfectly equalized bipolar signals." This apparatus features a delay line with a reset control, an AND gate, and a one-shot multivibrator. It is utilized alongside an adaptive equalizer, with the output of the equalizer connected to the input of the invention's apparatus. The design effectively removes narrow pulses from the signal, ensuring that the output contains pulses of equal length, thus enhancing signal integrity.
