隨著製程不斷進步，數位電路在運算處理能力與操作速度上發展迅速，並且能夠儲存大量的數位資訊，許多類比電路已逐漸改由位數電路的方式呈現，但是即使如此，電路與外界傳遞或接收資訊還是必須透過類比數位轉換器與數位類比轉換器來實現。為了實現低功率消耗且高速資料傳輸的電路，本研究使用包含前景式數位校正電路、Virtual Ground Reference Buffer、Switch Boostrapped…等等電路設計技巧來實現每秒取樣兩億次十位元脈管式類比數位轉換器，使的電路能夠在低功率消耗的情況下讓效能提高，以符合電子電路發展趨勢。

類比數位轉換器特性在輸入全擺幅正弦波，頻率為4.5 MHz 正弦波模擬結果能得到為雜訊位準-85 dB，訊號對雜訊及失真比61.6 dB。在供應電壓源為1.8伏特時所消耗的功率為68.5mW，另外，在輸入全擺幅正弦波，頻率為10 MHz 正弦波量測結果能得到為雜訊位準-40 dB，訊號對雜訊及失真比24.8 dB。晶片面積含I/O Pads 約為2.52 mm2，並採用TSMC 0.18μm 1P6M Standard CMOS製程加以實現並封裝。

A 10-bit 200-MS/s pipelined analog-to-digital converter (ADC) using virtual ground reference buffer and foreground calibration technique in TSMC 0.18μm standard CMOS process technology is presented.

The simulated ADC performances achieve -85 dB of Noise Level , 61.6dB of SNDR for 4.5MHz input signal. Under 1.8-V supply, the power consumption of the proposed ADC is 68.5-mW. The measured ADC performances achieve -40 dB of Noise Level, 24.8 dB of SNDR for 10MHz input signal. The chip area including I/O pads is 2.52 mm2.
