Description

2 kinds of wide bandwidth,low voltage GaAs operational amplifiers (op amps),a high open-loop gain op amp and a high speed op amp,were designed with 0.5μm GaAs MESFET technology and newly d eveloped differential amplifiers.Calculated open-loop gain A_0, unity gain frequency f_T,common mode rejection ratio(CMRR) and power dissipation P were 62.1dB,1.54GHz,63.1dB and 131mW, respectively for the high gain op amp.Sirilarly,A_0=57.5dB,f_T=1. 86GHz,CMRR=61.9dB,P=172mW were obtained for the high speed op amp. Power supply voltages were V_DD>=1V and V_SS>=-1V.
