An 8Bit 2ns Monolithic DAC

An 8-bit resolution ultra-high-speed monolithic digital-to-analog converter (DAC) is fabricated using super self-aligned process technology (SST). In order to improvedynamic8CCUIK)', wbidI is determined by settling speed, clock feed through noise, and glitch,a number of new circuit technologies Ire developed including a rise - and fall-time control switch driver. a low-noise flip-flop, and a differential buffer configuration. In addition, a new clip assembly technology is developed employing a multilayer ceramic substrate. Performance measurements show a settling time to 8-bit accuracy of about 2 ns, a maximum conversion rate of 1 GHz, a glitch energy of 2 ps.V, and a 10-bit linearity error accuracy without trimming.
