The circuit in Figure 1 converts
pulse information to a clean dc voltage
by the end of a single incoming
pulse. In another technique, an RC filter
can convert a PWM signal to an averaged
dc voltage, but this method is slow in responding.

This circuit is intended to provide good square waves converting a sine wave picked-up from an existing generator. Its main feature consists in the fact that no power-source is needed: thus it can be simply connected between a sine wave generator and the....

This Circuit is a zero crossing detector, which produces an output state change whenever the input crosses the reference input. In this case the reference input is connected to ground. The output of the comparator can easily drive multiple outputs, which can....

The voltage-to-current converter in Figure 1 can both source and sink current. The circuit is more flexible than some traditional current references that require different topologies for current sourcing and sinking. Also, you can easily adjust the value of....

The voltage-to-current (V/I) converter in Figure 1 uses three common op amps, two medium-power transistors, and only a few passive components. The first op amp (IC1) inverts the sum of voltages VIN and VOUT to V1=-(VIN+VOUT). The second op amp (IC2) and....

application notes of years ago, detailing
the use of unbuffered U-type inverters
for use in ring oscillators. The
application notes circuit consists of only
the inverters. The circuit....

This is a 0 - 6 MHz DDS VFO controlled by a PIC16F84 (or `C84).
The VFO is separated into two modules, the DDS module and
the controller module. The PCB layout (double sided) for
the DDS module is included as two Postscript files
(scale 1:1). The .PS....
