With increasing interest in current-mode analogue processing due to its high
performance properties such as speed, bandwidth and accuracy compared to voltage-mode
processing, new current-mode alternatives to various conventional circuit designs are
appearing. In this report, a novel circuit design to construct a fully-differential current-mode
operational amplifier ( OP-AMP ) is suggested. A standard CMOS process and a 5
volt power supply are utilized. Simulation results using SPICE are presented. For the
current-amplifier, a highly linear behavior ( THD 0.02% ) and an excellent frequency
response ( 10 MHz ) were observed. Using this new differential OP-AMP topology,
fully-differential switched-current delay cell and an integrator circuit were also developed
successfully. / Graduation date: 1991
