Title: Scott N Swisher: Innovator in Frequency Synthesis and Power Supply Technology
Introduction
Scott N Swisher is a notable inventor based in Elk Grove, IL (US). He has made significant contributions to the fields of frequency synthesis and power supply technology. With a total of 2 patents, his work has had a considerable impact on the industry.
Latest Patents
One of his latest patents is the "Synchronized frequency synthesizer with high speed lock." This innovative frequency synthesizer utilizes a first-order loop and a sample-and-hold phase detector with optimized gain to achieve very fast frequency locking characteristics. Additionally, it incorporates synchronization of the programming of the loop divider and the range shifting of the voltage-controlled oscillator. An adaptive loop filter is also provided, allowing the first-order loop to be used for lock acquisition while maintaining excellent noise performance after the lock has been obtained.
Another significant patent is the "Active power supply ripple filter." This active power supply ripple filter features low noise and low power dissipation characteristics. It tracks the voltage of the power source with minimal voltage drop and high current capability. The circuit consists of a control transistor connected between one terminal of a power source and one terminal of a load, a reference circuit that tracks the supply voltage, a low pass filter that filters the reference voltage, and an amplifier that drives the control transistor in response to the filtered reference voltage and feedback voltage from the load. This design minimizes the voltage drop across the control transistor and reduces the capacitance values required for the filter capacitors.
