INTEGRATOR CIRCUIT OF WIRELESS IR RECEIVER, WIRELESS IR RECEIVER COMPRISING THE SAME INTEGRATOR CIRCUIT, AND METHOD FOR CONTROLLING A INTEGRATION SIGNAL

摘要

PURPOSE: An integral circuit of a wireless IR receiver, the wireless IR receiver including the same, and a method for controlling an integral signal are provided to control a pulse width by controlling rising time and falling time of the integral signal outputted from the integral circuit. CONSTITUTION: An integral circuit(60) changes an amount of currents of a circuit according to the switching of a fusing circuit(80). The integral circuit controls a pulse width of an output signal outputted through a capacitor. The integral circuit includes a plurality of switches(SW1R,SW2R,SW3R,SW1F,SW2F,SW3F) which are turned on or off according to a switching signal applied from the fusing circuit. The capacitor is charged or discharged by constant current sources(I1R,I2R,I3R,I1F,I2F,I3F).
