This paper describes a 12-bit, 40-MS/s pipelined A/D converter (ADC) which is implemented in 0.18-μm CMOS process drawing 76-mW power from 3.3-V supply. Multi-bit architectures as well as telescopic operational tra...
Noise and mismatch are important error sources in pipeline ADCs,so careful calculation and system simulation are carried out using Matlab software. To reduce power consumption while not lose performance, the amplifier...
A low-power-consumption 9bit 10MS/s pipeline ADC,used in a CMOS image sensor,is proposed. In the design, the decrease of power consumption is achieved by applying low-power-consumption and large-output-swing amplifier...
