A. Chelouah et al., Improved current mirror for increasing phase margin of X-band GaAs pseudo-operational amplifiers, MICROW OPT, 24(3), 2000, pp. 166-168
An original concept is presented for increasing the performance of a pseudo
-operational amplifier. This concept proposes a current mirror in which an
inductance improves its gain and phase at very high frequencies. Using this
structure in the design of a GaAs pseudo-operational amplifier, very promi
sing simulation and experimental results are obtained. (C) 2000 John Wiley
