Abstract :
A dynamic range boosting (DRB) technique is proposed in this paper. By applying this technique, the designed pipelined analog-to-digital converter could sample a wide dynamic range analog input, which is even larger than the output swing of the opamp used in SHA and MDAC. A 13b 5MS/s pipelined A/D converter based on single stage telescopic opamps is implemented and achieves a dynamic range up to 2.4Vpp, while its supply voltage is 1.8V.
