Title: Colin Weltin-Wu: Innovator in Digital Frequency Synthesis

Introduction

Colin Weltin-Wu is a notable inventor based in Mountain View, CA. He has made significant contributions to the field of digital frequency synthesis, holding 2 patents that showcase his innovative approach to technology. His work primarily focuses on enhancing the performance and efficiency of digital-to-time converters and frequency synthesizers.

Latest Patents

Colin's latest patents include a "Time-interleaved digital-to-time converter" and a "Frequency synthesizer with hit-less transitions between frequency- and phase-locked modes." The first patent describes a fractional-N divider that supplies a divided clock signal. It generates an adjusted divided clock signal in a digital-to-time converter circuit, which has a delay linearly proportional to digital quantization errors of the fractional-N divider. The charging of capacitors in this circuit is interleaved, allowing for precise timing adjustments.

The second patent focuses on a digital frequency synthesizer that provides absolute phase lock and shorter settling time. This is achieved through a digital filter that incorporates both phase and frequency paths. The control logic in this synthesizer disables the frequency path during acquisition, ensuring a wide bandwidth. Once frequency acquisition is complete, the output phase is adjusted to achieve a tighter phase lock.
