Title: The Innovations of Frederick Carnegie Thompson

Introduction

Frederick Carnegie Thompson is a notable inventor based in Foynes, Ireland. He holds a total of eight patents, showcasing his significant contributions to the field of electronics and data conversion technologies. His work has had a profound impact on the development of advanced electronic systems.

Latest Patents

Thompson's latest patents include an innovative analog-to-digital converter that utilizes a discrete time comparator and a switched capacitor charge pump. This 'all-digital' operational amplifier architecture eliminates the need for devices to remain in their saturation region. It leverages high-speed capabilities achievable through deeply scaled technology, replacing traditional linear current-referenced continuous-time operational amplifier circuits with dynamic circuits that require no referencing structure. These circuits also have no static power consumption and are compatible with ultra-low supply voltages.

Another significant patent involves jitter reduction techniques when using digital phase-locked loops (PLLs) with analog-to-digital converters (ADCs) and digital-to-analog converters (DACs). This system includes a primary ADC circuit that samples an input signal and produces a digital output signal. It also features a slope calculation circuit, a digital PLL circuit, a sampling error circuit, and a summing circuit. The slope calculation circuit generates a digital slope signal, while the DPLL provides a sampling clock signal to the primary ADC circuit. The sampling error circuit generates a signal representative of sampling error, which is then adjusted by the summing circuit to produce an accurate digital output signal.
