| 2. | The cmos technology is better than bipolar technology , which help the circuit get lower power , so it is adopted . the hspice is used for dac circuit simulation with tsmc 0 . 18 m bsim3 ( v3 . 1 ) cmos model 从集成度、功耗、成品率等方面考虑, cmos工艺明显优于双极型工艺,故本设计采用cmos工艺,并用tsmc0 . 18 mbsim3 ( v3 . 1 ) cmos工艺模型在hspice软件上完成电路模拟仿真。 |
