Abstract
A circuit for controlling time sequence of an electronic device, the circuit comprises a delay unit to receive a first control signal, a first switch unit connected to the delay unit to receive the first control signal after a rising edge of the first control signal, a second switch unit to promptly receive the first control signal in response to a falling edge of the first control signal, and a voltage output unit connected to the first and second switch units. The voltage output unit is selectively controlled by the first or the second switch unit to output a second or a third control signal to turn on or off the electronic device.
Claims9
A circuit for controlling time sequence of an electronic device, the circuit comprising:
- a delay unit to receive a first control signal to delay the first control signal for a period of time;
- a first switch unit connected to the delay unit, to receive the delayed first control signal;
- a second switch unit to receive the first control signal;
- and
- a voltage output unit connected to the first and second switch units, wherein the voltage output unit is controlled by the first switch unit to output a second control signal after a rising edge of the delayed first control signal, to turn on the electronic device;
- wherein the voltage output unit is controlled by the second switch unit to output a third control signal in response to a falling edge of the first control signal, to turn off the electronic device.

- a delay unit to receive a first control signal to delay the first control signal for a period of time;
- a first switch unit connected to the delay unit to receive the delay first control signal, and output a first signal;
- a second switch unit to receive the first control signal, and output a second signal;
- and
- a voltage output unit connected to the first and second switch units to receive the first and second signals, and output a second control signal to the electronic device according to the first and second signals, wherein the voltage output unit is controlled by the first signal after a rising edge of the delayed first control signal to output the second control signal to turn on the electronic device, and the voltage output unit is controlled by the second signal in response to a falling edge of the first control signal to output the second control signal to turn off the electronic device, wherein a falling edge of the second control signal is delayed for a period of time after the rising edge of the first control signal, a rising edge of the second control signal occurs nearly at the same time as the falling edge of the first control signal.
