Figure 1 shows a novel circuit that uses a low-cost, high-speed op amp as a crystal-controlled RF sine-wave oscillator. An op-amp oscillator offers several advantages. Because an op amp is a complete amplifier with a high-impedance input and a low-impedance output, it considerably simplifies the circuit design by replacing the traditional multiple-transistor circuit with its interstage transformer and numerous other components. …
