Programmable-logic devices provide a popular method of implementing complex functions in digital designs. Although manufacturers don't yet offer analog circuits whose complexity compares to VLSI ...

In Part one, we discussed many different low cost circuits and architectures for temperature sensing. Here is Part two with unique design and architecture examples of temperature sensing. Sine waves ...

Fig 1. Two analog multipliers form a VCO with quadrature outputs, while a third multiplier provides AGC to stabilize output voltages without adding distortion. Fig 2. The oscilloscope trace of the VCO ...

The circuit of Figure 1 generates sinusoids down to very low frequencies with distortion in the region of 3% or less, yet has no feedback or gain-stabilizing components because none are needed. It ...
