Generator Schaltung. Figure 5 shows the miller integration ramp generator. The circuit invented by villard was just the diode clamp cell of the circuit.
A high gain amplifier. In fact villard circuit is a misnomer for any of these circuits as i explained in the voltage doubler article. A y product folder sample buy technical documents tools software support community an important notice at the end of this data sheet addresses availability warranty changes use in safety critical applications.
In our product development cycle we ve used circuitlab in more places than you might expect.
My german is not too wonderful but my understanding of the article is that villard schaltung means a single stage of the multiplier ie a voltage doubler.

Miller integrator ramp generator figure 5. The given project describes how different dtmf tones can be generated using dtmf tone generator chip 91214b and how these tones can be decoded by dtmf decoder chip mt8870 that generates 4 bit digital output using these two circuits together one can build dtmf based remote control application in which 91214b chip is used as remote control and mt8870 is used at the receiver side to decode dtmf.
