A simple AM transistor radio can be made with surprisingly few components, but for a circuit with a reasonable ... that’s one for the self-oscillating mixer, one for IF, an audio preamplifier ...
with a self-oscillating mixer, 455 kHz IF amplifier, and class AB audio amplifier. The devices are a little archaic by today’s standards, with comically low-gain germanium transistors and ...
Active inductors are becoming increasingly important in the design of radio frequency (RF ... A circuit component that mimics the behavior of an inductor using active devices like transistors ...
