Title: Threshold value setting circuit
Inventor: YAMAMOTO YUJI
IPC: H03K5/08
Filed: 2000-03-23
Abstract: PROBLEM TO BE SOLVED: To provide a threshold value setting circuit that does not employs a diode and a high resistance resistor. SOLUTION: A transconductance 3 compares a voltage at an input 2 with a voltage of a capacitor C1 and outputs a current output Iout proportional to the result of comparison. The current output Iout charges the capacitor C1 through current mirror M16, M17 and the capacitor C1 holds a peak value of the input 2. By supplying a constant current to transistors(TRs) M14, M15, a power supply voltage is set to the gate voltage of the current mirror M16, M17 while the capacitor C1 holds the peak value to completely shut off the current mirror M16, M17. A TR M11 whose gate electrode level is fixed discharges the charge stored in the capacitor C1.  An IV conversion circuit consisting of a differential amplifier and TRs M23, M24, M25 converts the voltage across the capacitor C1 into a current, which is supplied through a resistor R12 and a voltage across the resistor R12 is used for a threshold value VL. The threshold value is almost proportional to the peak value of the signal. Since no resistor is connected in parallel with the capacitor C1, the threshold value setting circuit requires no high resistance resistor.
