In this report, the design flow of a 2-stage operational amplifier (OpAmp) is presented from schematic to layout. The circuit meets all the specs in all the input corners (Vcm=650mV, 750mV and 850mV). The total power consumption under nominal case (Vcm=750mV) is 346.13uW, total ...
High power, high gain and low loss are realized with a two-stage optical amplifier suitable for use as a repeater for long haul optical communication systems, which uses back propagation pump light to cause a maximum inversion of the first stage amplification means in accordance with the principl...
A 2-stage 80 W amplifier, which consists of a 450 W saturated power GaN HEMT Doherty amplifier and a 30 W driver, was developed. At first we developed the 450 W GaN HEMT Doherty amplifier and obtained saturation power of 56.5 dBm(450 W) and drain efficiency of 55% at 6 dB back-off...
