Abstract :
An ultra-wideband 7-bit 5 Gsps analog-to-digital converter (ADC), fabricated in a 4-level interconnect, 0.8 um InP HBT technology, is presented. This monolithic ADC achieves 6 effective number of bits (ENoB) Nyquist performance at a sample rate of 5 Gsps. Furthermore, an ENoB performance of greater than 5.5 is maintained at analog input frequencies up to 7.5 GHz. This effective resolution-bandwidth product performance is significantly higher than any other previously reported monolithic ADC with sample rate ges 3 Gsps.
