Title: The Innovations of Richard L. Harwood

Introduction

Richard L. Harwood is an accomplished inventor based in Westford, MA (US). He has made significant contributions to the field of electronic systems, holding a total of 3 patents. His work primarily focuses on enhancing the performance and efficiency of voltage-controlled oscillators and clock alignment systems.

Latest Patents

One of Harwood's latest patents is titled "Continuous tuning of digitally switched voltage-controlled oscillator frequency bands." This invention features a phase-locked loop (PLL) control system that includes a voltage-controlled oscillator (VCO) circuit. The circuit comprises an inductor and multiple capacitors arranged in parallel with the inductor. By digitally enabling or disabling the capacitors in a thermometer-coded manner, Harwood's design creates tuning states that expand the frequency range of the VCO. This innovation allows for a wider continuous VCO frequency tuning range, which is particularly useful under changing operating conditions.

Another notable patent is the "Clock alignment system having a dual-loop delay-locked loop." This system includes a first clock generator that produces a clock signal in one domain and a second clock generator that generates a slower clock signal in another domain. The invention employs a coarse delay-locked loop (DLL) to generate clock signals with phase offsets and a fine DLL to adjust the phase of a selected clock signal. This technology ensures precise alignment of clock signals, enhancing the overall performance of electronic systems.
