A circuit structured to energize another device, the circuit comprising: a capacitor structured to at least temporarily store a charge and having a first terminal and a second terminal; a portion of the circuit comprising a first transistor having a threshold voltage and a Zener diode having a breakdown voltage and being connected between the first terminal of the capacitor and a gate of the first transistor, the portion of the circuit being structured to discharge a first portion of the charge at a first rate while the voltage applied to the Zener diode exceeds the breakdown voltage and meets the threshold voltage; the portion of the circuit further comprising at least a first resistor that is connected with an electrode of the first transistor and that is structured to be further connected with the first terminal of the capacitor; another portion of the circuit comprising a second transistor and being structured to discharge a second portion of the charge subsequent to the discharge of the first portion of the charge and at a second rate greater than the first rate beginning at the point when the voltage applied to the Zener diode no longer meets the threshold voltage; and the capacitor having stored therein prior to the onset of the discharge of the second portion of the charge a portion of the charge sufficient to energize the other device; and the resistance of the first resistor and the breakdown voltage of the Zener diode being selected to cause the capacitor to retain for at least a predetermined period of time during the discharge of the first portion of the charge the portion of the charge sufficient to energize the other device. a capacitor structured to at least temporarily store a charge and having a first terminal and a second terminal; a portion of the circuit comprising a first transistor having a threshold voltage and a Zener diode having a breakdown voltage and being connected between the first terminal of the capacitor and a gate of the first transistor, the portion of the circuit being structured to discharge a first portion of the charge at a first rate while the voltage applied to the Zener diode exceeds the breakdown voltage and meets the threshold voltage; the portion of the circuit further comprising at least a first resistor that is connected with an electrode of the first transistor and that is structured to be further connected with the first terminal of the capacitor; another portion of the circuit comprising a second transistor and being structured to discharge a second portion of the charge subsequent to the discharge of the first portion of the charge and at a second rate greater than the first rate beginning at the point when the voltage applied to the Zener diode no longer meets the threshold voltage; and the capacitor having stored therein prior to the onset of the discharge of the second portion of the charge a portion of the charge sufficient to energize the other device; and the resistance of the first resistor and the breakdown voltage of the Zener diode being selected to cause the capacitor to retain for at least a predetermined period of time during the discharge of the first portion of the charge the portion of the charge sufficient to energize the other device.
