摘要：
PROBLEM TO BE SOLVED: To provide a current mode AD converter for improving linearity of a VIC and widening the band of an ADC.
SOLUTION: The current mode AD converter includes: a VI converter 10 for converting the input analog voltage value of differential signals to the input analog current value of operation signals; and a current mode pipeline type AD converter 15 which has an 1.5-bit redundant conversion function, for AD converting the input analog current value of the differential signals which is the output of the VI converter. The VI converter 10 includes: an amplifier whose voltage gain is -A times; a transistor wherein the input of the amplifier is connected to a source, the output of the amplifier is connected to a gate and negative feedback is applied; a resistor; and a constant current source.
