This work presents a topology proposal of a 0.35um CMOS cascode low noise amplifier using an active inductor. The inductance required to output of cascode pair is synthesized by an active inductor in Compact Wu Folded configuration. The LNA presents a gain of 12.04 dB with a noise figure of 4.78 dB at 1.8 GHz. The layout is presented occupying an active area of 0.165 mm2. The results are satisfactory,...
DC suppression consists of a mandatory procedure in several measurement applications. In many situations, its value is orders of magnitude above the desired information to be measured. In fully-differential instrumentation amplifiers, which present a very high common-mode rejection ratio, matched coupling capacitors are demanded for CMRR not to degrade. Stability problems can arise if active cancellation...
