Title: The Innovations of Boris Drakhlis

Introduction

Boris Drakhlis is a notable inventor based in Mountain View, CA. He has made significant contributions to the field of electronics, particularly in the development of crystal oscillators. With a total of 2 patents to his name, Drakhlis continues to push the boundaries of innovation in his field.

Latest Patents

One of his latest patents is a crystal clock generator operating at the third overtone of the crystal's fundamental frequency. This invention describes a crystal oscillator that operates at the third overtone, where a specific value of a shunt resistor is chosen to ensure that the absolute value of the product gm × (Xc) × (Xc) exceeds the effective reactance of the crystal. Here, gm represents the gain of the amplifier connected to the phase-shift legs, while Xc denotes the effective capacitive reactances at the respective nodes. The third overtone is then doubled by a multiplier, and the final output is filtered to eliminate the third overtone, selecting a frequency six times the fundamental frequency. Additionally, a pair of Colpitts or Pierce amplifier half circuits is connected to the phase-shift leg nodes, which can be capacitively isolated from the Pierce-amplifier circuit nodes to enhance start-up. Frequency doubling can also be achieved by summing currents from the two oscillator half circuits.
