PURPOSE:To reduce the power consumption by connecting a depression FET to a capacitor, which is charged through a charging resistance, in parallel and by controlling its impedance. CONSTITUTION:The P-channel depression FET is connected to the capacitor C1 in parallel, its source electrode is connected to the connection point between the capacitor C1 and the charging resistance R2, the gate electrode is done to the power supply Vcc, the Zener diode ZD2 is put in parallel with the capacitor C1 and its cathode is connected to the connection point between the capacitor C1 and the resistance R2. |
