The device is a dual Intermediate-frequency amplifier (IFA) which consists of 4-stage amplifier with tunable gain, an input linear buffer for analog o ...
The venerable superheterodyne is very much with us. The intermediate frequency amplifier, the IF amplifier or the IF stage, requires alignment of the IF transformers for optimum performance so let's ...
Intermediate-frequency amplifier consists of 2-stages amplifier, output buffer with tunable gain and two LDO voltage regulators. Each stage of the am ...
This circuit in Figure 1 produces the amplitude curve illustrated in Figure 2. 2. Wideband Response for Circuit of Figure 1. The voltage gain of the op amp stage itself is 20, but this is cut in half ...
