Qualitative Analysis of High Gain Small-signal Amplifier with MOSFET Current Mirror
free download

A small-signal high voltage gain amplifier with two identical MOSFET current mirrors is proposed and analyzed on the qualitative scale. In the narrow band (bandwidth 4.093 KHz) performance range, the proposed amplifier produces high voltage gain (141.883), almost Therefore, we start this book with discussions about differential amplifiers (DIFAs) and their gain and behaviour concerning noise production. Four chapters will dive deep into the matter. They also include a practical example with calculation, simulation, and measurement results. In additional
