Abstract:
1. A circuit, comprising: a main driver configured to provide a charging signal in response to a trigger pulse; and an output section comprising a plurality of output circuits arranged to receive the charging signal, wherein each of said plurality of output circuits is configured to provide an output signal in response to the charging signal and a different clock signal, said plurality of output circuits comprising a first output circuit and a second output circuit, wherein the output signal provided in the first output circuit is in response to the charging signal and a first clock signal, and the output signal provided in the second output circuit is in response to the charging signal and a second clock signal subsequent to the first clock signal, wherein the main driver comprises: a first switching element comprising an output end and a controlling end, the controlling end arranged to receive the trigger pulse and the output end arranged to provide the charging signal, the first switching element operable in a conducting state in response to the trigger pulse; a second switching element comprising a first end electrically connected to the output end of the first switching element, a second end connected to a voltage source, and a controlling end arranged to receive a second pulse subsequent to the trigger pulse for resetting the charging signal, wherein the second switching element is operable in a conducting state in response to the second pulse so as to electrically connect the output end of the first switching element to the voltage source; a third switching element comprising a first end, a second end connected to the voltage source, and a controlling end connected to the output end of the first switching element, wherein the first end is arranged to receive the first clock signal and wherein the third switching element is operable in a conducting state in response to the charging signal; and a fourth switching element comprising a first end connected to the output end of the first switching element, a second end connected to the voltage source, and a controlling end arranged to receive the first clock signal.
