Maximum input voltage so that no clipping occurs [on hold]

Suppose we have a combination (dual) clipper circuit with two diodes. What is the maximum input voltage width so that no clipping occurs at all? Is it 0V because in any case at least a really small ...

Series diode voltage clipper, on Multisim clipping and shifting on positive and negative voltage

This is my circuit: I’m testing a Series diode clipper circuit, and the end result should be this: (I've used 5V in my circuit, not 10V like in this plot, but this is not the issue) Instead what ...

TDA7231A seems to be clipping all the time

Final update: I got two more chips today and started experimenting with them. I tried both adding a 10 k resistor from C4 to the ground and the circuit in JIm Dearden's answer. His circuit helped a ...

How to improve nasty form clipping behavior in differential input stage

The amplifier in the following schematic, when simulated, shows that it can cleanly amplify a signal with 0.1V amplitude to 10V. When driven with a larger signal, though, the behavior is very nasty in ...
