Improving Input Circuits for 7-bit Flash AD Converter
The development of the flash analog-digital converter (ADC) includes mainly the design of the input comparators. This paper deals with the design and improvement of the high-speed comparator for a 7-bit Flash ADC for Ultra-Wideband (UWB) sensor systems. The comparator is designed in 0.35 µm SiGe BiCMOS technology by AMS. Proposed comparator achieves 480 MHz bandwidth with 1 mV input resolution at signal range 1.6 Vpp. The power consumption of the designed comparator cell is 5.9 mW at -3.3 V power supply. The improved comparator was compared with the previous one designed for 4-bit flash ADC. For comparison, the basic parameters of the post-layout simulations were performed.
