摘　　要：本文设计实现了一种低压的开关电容滤波器,该电路采用上华0.8微米标准CMOS工艺实现。本电路是基于一种新的时钟倍增电路实现的一个双二阶带通滤波器,测试结果表明该带通滤波器可以在1V电源电压下正常工作,测试结果与仿真一致。A low voltage switched-capacitor biquad band-pass filter based on a new clock-boosting circuit is presented in this paper. It is implemented in CSMC standard 0.8μm CMOS technology. Measured results show that the chip can operate at 1V supply. The measured frequency response accurately agrees with the simulated results.
