Abstract :
In this work, a new termination technique for the averaging network of the flash analog-to-digital converter (ADC) input pre-amplifiers is devised. The proposed technique allows efficient suppression of pre-amplifiers offset voltage while consuming no over-range voltage headroom. This makes it suitable for deep-submicron technologies. This technique is applied to the design of a 2.5GS/S flash ADC in 0.13mum CMOS technology to estimate the resulting saving in the input capacitance and power dissipation of the pre-amplifier array
