چکیده انگلیسی
In this paper, a high accuracy CMOS differential input current buffer (CB) is proposed which employs super source followers (SSF) as input stage and regulated cascode (RGC) current mirrors as output stage. High accuracy requires very high output resistance and low input resistance. Small signal analysis is performed and it is shown that the proposed CB circuit has very low input impedances at ports n and p due to SSF transistors and also very high output impedance at output port due to RGC current mirrors. The simulation results show 9.72 Ω input resistances at ports n and p, 454 MΩ output resistance at output port with only 625 μW power consumption under ±0.9 V power supplies. The simulations are performed with HSpice using TSMC 0.18 μm process parameters and it is shown that the simulation results are in very good agreement with the theoretical ones.
