This circuit was born from an application that required an input signal to be precisely clamped to less than 2.5 V, while operating on a 2.5 V supply (actually a reference) with a maximum output of 4 ...

And here it is, modelled using LTSpice. It is the same circuit as the classic simple precision rectifier (set to pass the negative half-sine), but with the non-inverting input of the op-amp connected ...

Voltage clamps for protecting low-voltage dc circuits require a new approach to circuit design. Many commonly used voltage clamps were built for systems of 5 V or higher, but lower-voltage systems ...

IXYS Corporation announced that its wholly owned UK subsidiary, IXYS UK Westcode Ltd., launched its new range of precision bar clamps for use with its comprehensive range of press-pack semiconductors.
