Abstract
An integrated circuit for measuring a signal, including a parametric pin measurement unit (PPMU) that sends a forced signal, the PPMU having a first amplifier, a second amplifier with an output terminal connected to the input terminals of the first amplifier through a common resistor; a voltage-to-current convertor connected to a PPMU output and having a first output and a second output; n channel MOSFETs connected to the first output of the voltage-to-current converter; p channel MOSFETs connected to the second output of the voltage-to-current converter; a buffered amplifier connected to an output port between the n channel MOSFETs and the p channel MOSFETs; and a resistance divider connected to the output of the buffered amplifier.
