Switched-capacitor blocks are easily ... Adding an external pass transistor and current-setting resistor enables easy construction of a programmable current source. Figure 1 shows a classic ...

In this video, he shows how to replace a bias resistor (and consequently an additional capacitor) with a current source for both common-emitter and common-collector amplifiers. A current source ...

A positive temperature coefficient resistor ... parallel to the run capacitor. In other words, it is wired in series with the start winding and in parallel with the run winding. (See Figure 3.) When ...
