A Multiple-Output Current Mirror with Neuron MOSFETs
Akio Shimizu,Yuki Nobe,Yohei Ishikawa,Sumio Fukai 대한전자공학회 2009 ITC-CSCC :International Technical Conference on Ci Vol.2009 No.7
In this paper, we propose a multiple-output current mirror with neuron MOSFETs. The proposed circuit is composed of a transimpedance amplifier with multiple-output. Consequently, the proposed circuit has high current copy accuracy and a high output swing. Then the proposed circuit has two output terminals for a high performance operational amplifier and a high resolution digital-to-analog converter. The proposed circuit is designed by using the device parameter of the standard CMOS 1.2㎛ process. The performance of the proposed circuit is evaluated by HSPICE simulation. Simulation results show that the error rate of current copy in the proposed circuit is ±0.001[%] when output voltage is 0.13[V] and over.
