Who would have thought that a circuit comprising only two 2-input NAND gates could be so complicated (or, should we say, “interesting”)? Up to this point (click here to see my earlier columns), the ...

The output frequency of the simple VCO in Figure 1, which is synthesized from inverting latch stages, is tunable to an integer multiple of the input frequency by selecting which output phases feed ...

How to build a circuit that converts capacitance into a pulse train. Test results of the circuit design. The circuit in Figure 1 allows you to convert capacitance into a pulse train by using a ...
