Application NoteAnalog
High Speed Comparator Techniques (AN13)
A guide by Jim Williams on high-speed comparator design using the LT1016, covering parasitic management, grounding, and applications like V/F converters and sample-and-hold circuits.
Overview
This application note, authored by Jim Williams, provides an in-depth exploration of high-speed comparator techniques centered on the LT1016. It addresses the practical challenges of working with 10ns response times, including bypassing, grounding, probe compensation, and the effects of parasitic capacitance. The document features numerous high-performance circuit designs such as 10MHz and 30MHz V/F converters, high-speed sample-and-hold circuits, a 12-bit A/D converter, and a 12ns circuit breaker. Appendices offer technical guidance on bypass capacitors, ground planes, and measuring equipment response.
Use Cases
