Design and Analysis of Low Power Gm_OTA Which Contains Bandgap Reference
Yicheng Zhao · Journal of Liaoning University · 2011
In this article,a design method of low power Gm_OTA which contains bandgap reference,the construction and neaten of circuit are finished in schematic of Candence,and the basic struction is analyzed.Basis on that,the system model is also established by Hspice Tool.At the same time,the simulation of the system model are accomplished through.Under 7.75V,on the basis of csmc 0.5um technics model,75pF load is drived by the design,the phasic margin is 135 degree,the unit plus bandwidth is 1.19MHz,the static power is 3.43mW,and good capability of low power Gm_OTA is carried out.
