This article describes a method on how to configure the operational amplifier as a phase detector or a frequency mixer using its disable pin. There are several operational amplifiers which provide a disable pin that parallels outputs for video multiplexing. By switching the gain of the circuit's ...
when the op amp is connected to the output of the phase detector, this voltage can improperly bias the diodes in the phase detector and cause an unbalance in the diode circuit.

A phase-locked loop (Figure 1) is a feedback system in which a phase comparator or detector drives a VCO in a feedback loop to make the oscillator frequency (or phase) accurately track that of an applied reference frequency. A filter circuit is typically required to integrate and smooth th...
Seriously, I am not sure what uses are there for bang-bang circuit. Implementation-wise: using both clock edges will have burden on timing closure. FPGAs are not good for controlling delay and the data transitions are meant to be ignored from say a rising edge to a rising edge. For ...
circuit that's both frequency- and phase-sensitive. A PLL is not a single component, but a system that consists of both analog and digital components -- interconnected in a "negative feedback" configuration. Consider it analogous to an elaborate operational amp (op amp)-basedamplifiercircuit. ...
Circuit Variability: By adjusting the capacitors, often through gang-tuning, the frequency of the RC phase shift oscillator can be finely tuned to meet specific needs. What is Oscillator: An oscillator, like the RC phase shift type, is a device that generates a repetitive electronic signal, oft...
If implemented in a product, a lock acquisition circuit is needed. This was not demonstrated. VTUNE needs to be “precharged” to steer the VCO frequency close enough to the reference so that lock can be captured. In Figure 19, the measured phase noise results were impressive using the HMC...
Normally such controllers are realized with an MCU and software, the novelty of this circuit realizing the same function without using the MCU, thus making it simple with low cost components. Finally, a prototype of the cycle skipping controller can be seen inFigure 4. ...
