摘要
提出了一种分辨率为12位，信号带宽为5mhz的连续时间σ - δ调制器。仿真结果表明，采用中芯国际0.18 um CMOS工艺，在1.8 V电源下功耗为20 mW。
A 20mW 200MHz CMOS continuous-time sigma-delta modulator with 5MHz signal bandwidth and 12 bits of resolution
A continuous-time sigma-delta modulator with 12 bits of resolution over a signal bandwidth of 5 MHz is presented. The simulation results show that it consumes 20 mW from a 1.8 V power supply, utilizing SMIC 0.18-um CMOS process.
