Abstract |
In this paper, the pipelined A/D converter with multi S/H stage structure is proposed for high resolution and high-speed data conversion rate. In order to improve a resolution and operational speed, the proposed structure increased the sampling time that is sampled input signal. In order to verify the operation characteristics, 20MS/s pipelined A/D converter is designed with two S/H stage. The simulation result shows that INL and DNL are 0.52LSB ~-0.63LSB and 0.53LSB ~-0.56LSB, respectively. Also, the designed Analog-to-Digital converter has the SNR of 43dB and power consumption is 18.5mW. |
