Overlap clocking technique for 10 bit 50 MHz 3 V D/A converter

A 10-bit high-speed Digital-to-Analog (D/A) converter with small silicon area has been designed and fabricated using a new technique of overlap clocking for current switching to achieve low glitch energy. Common centroid layout technique has been used to achieve 10 bit accuracy without using any trimming. The D/A converter achieves 30 pV.s glitch energy while operating at 50 MHz with 3 V supply.
