- Microcontroller controls analog phase shifterPhase shifters find use in a variety of circuits, but variation in amplifier and capacitance tolerances usually makes it difficult to control the exact phase shift that precise control circuitry requires. The circuit in...Oct 21, 2020
- Use Variable DC Voltage To Control 70-MHz Output Phase ShifterIn many situations, designers must control the phase of an output signal in order to make certain circuits work properly. At low frequencies, an op amp can be used to vary the phase. But as the frequency gets into the...Jun 7, 2018
- Input Clock Adjusts Frequency of Digital Ramp GeneratorIt’s not always easy to design a ramp generator whose ramping frequency can be changed without manipulation of capacitors or inductors. Many ramp circuit designs are available, but they may not be flexible when it...Mar 19, 2018
- Zero-Crossing Circuit Avoids AC NoiseTo properly control AC sources using solid-state devices, you need a pulse to signal the start of the AC’s rising edge. Most of the time, however, tremendous noise levels plague power lines. There needs to be a...Feb 16, 2011
