Looking at the amplifier circuit shown in Figure 1, one could estimate how stable it is by determining the phase shift encountered when the signal goes around the loop one time, while the loop is ...

In the electronic field, an oscillator is a circuit capable of producing a self-sustained sinusoidal signal. In a lot of configurations, cranking up the oscillator involves the noise level inherent to ...

Even the simple circuit of Figure 1 seems to be suffering from a low phase margin condition as described in Reference 1 with a sharp resonance at 165MHz. It is important, even in lower speed signal ...
