Abstract
A signal integration circuit having a first MOSFET including a drain connected to a power source and a gate connected to a plural number of the first capacitances in parallel; and an input means connected to each capacitance; in which each input means comprises; the second MOSFET whose source is connected to the first capacitance through a resistance, which receives an input pulse signal, and whose gate is grounded through the second capacitance, and the third MOSFET whose source is connected to a gate of the second MOSFET, whose drain is connected to a power source, and whose gate receives a pulse signal for setting weight; a gate of the first MOSFET receiving a reference saw-tooth signal, a source of the first MOSFET grounded through the third capacitance, and an output pulse signal being output from this source of said first MOSFET.
