A CMOS four-channel*1K time memory LSI with 1-ns/b resolution

Abstract

A four-channel 1024-b time-to-digital converter chip, which records input signals to memory cells at 1-ns intervals, has been developed. To achieve 1-ns precision, the chip incorporates a feedback stabilized delay element. The chip was fabricated on a 5.0-mm*5.6-mm die using 0.8- mu m CMOS technology. It dissipates only 7 mW/channel under typical operating conditions. >
