| description | This project involves the design of a fully differential controlled-gain open-loop wideband amplifier on 0.18μm CMOS technology. The supply voltage is fixed at 1.8V and the circuit takes in a differential input voltage to provide a differential output voltage. The output common mode voltage is maintained at 0.9V through a common-mode feedback circuit. The performance of the wideband amplifier is defined by 8 specifications – AC differential gain, common mode gain, output voltage swing, unity gain bandwidth, current consumption, total harmonic distortion, settling time and the slew rate. Both bias circuit and the wideband amplifier are designed and circuit simulations are performed for typical mode as well as all process model corners using Cadence Virtuoso software. The layout of the circuit is completed followed by the post-layout simulation. The design was done on 0.5μm CMOS technology first before proceeding with the design on 0.18μm CMOS process. |
