Microwave Amplifier Design (part 1)
www.sjsu.eduA power amplifier is an ampl ifier that takes a low or intermediate level signal and significantly boosts its power level. At low frequencies this might be a trivial design which would only involve the careful choice of a DC bias circuit designed for maximum power output. But our ch osen amplifier design is

Low Cost Low Power Instrumentation Amplifier AD620
www.analog.comamplifier that requires only one external resistor to set gains of 1 to 10,000. Furthermore, the AD620 features 8-lead SOIC and DIP packaging that is smaller than discrete designs and offers lower power (only 1.3 mA max supply current), making it a good fit for battery-powered, portable (or remote) applications.

Audio Amplifier Circuit - UC Santa Barbara
web.ece.ucsb.eduspeakers have a low impedance, typically 8-Ohm. Even for a low-power 0.5W audio amplifier, PIR 2 /2 requires that the amplifier must be able to source a peak AC current of around 350 mA with an 8-Ohm load. This is a lot more than a typical op-amp is designed to provide. For example, the LM358 and LF353 (two op-amps used in this lab) can source

Phase sensitive detection: the lock-in amplifier
www.phys.utk.eduA lock-in, or phase-sensitive, amplifier is simply a fancy AC voltmeter. Along with the input, one supplies it with a periodic reference signal. The amplifier then responds only to the portion of the input signal that occurs at the reference frequency with a fixed phase relationship. By designing experiments that exploit this feature, it’s
