To improve the performance of the differential amplifier shown in Figure Q1, the biasing current source is replaced by a Widlar current source. The collector resistors are replaced by a current mirror formed by the matched bipolar transistors Qs and Q6, and the bipolar transistors Q1 and Q2 are replaced by the matched field-effect transistors M1 and M2. A single-sided output at the drain terminal of M2 is used. The transistor parameters for the bipolar transistors are: β = 100, VBE (on) = VEB(on) = 0.7 V, and VA = 100 V. The transistor parameters for M1 and M2 are: Kn = 0.15 mA/V2, VT N = 0.8 V, λ = 0.01 V-1 . The improved differential amplifier is shown in Figure Q2.
