The VCVS filter allows high Q factor and passband gain without the use of inductors. A VCVS filter also has the … See more The Sallen–Key topology is an electronic filter topology used to implement second-order active filters that is particularly valued for its simplicity. It is a degenerate form of a voltage-controlled voltage-source (VCVS) filter topology. See more VCVS filters are relatively resilient to component tolerance, but obtaining high Q factor may require extreme component value spread or high … See more An example of a unity-gain low-pass configuration is shown in Figure 2. An operational amplifier is used as the buffer here, although an emitter follower is also effective. This circuit is equivalent to the generic case above with See more • Filter design • Electronic filter topology • Harmonic oscillator • Resonance See more In 1955, Sallen and Key used vacuum tube cathode follower amplifiers; the cathode follower is a reasonable approximation to an amplifier with unity voltage gain. Modern analog filter implementations may use operational amplifiers (also called op amps). Because of … See more The generic unity-gain Sallen–Key filter topology implemented with a unity-gain operational amplifier is shown in Figure 1. The following analysis is based on the assumption that the operational amplifier is ideal. Because the op amp … See more An example of a non-unity-gain bandpass filter implemented with a VCVS filter is shown in Figure 5.
