Abstract:
1. An electronic circuit for generating a signal pulse comprising a front pulse and a rear pulse in a non-overlapping manner in reference to a reference signal, said circuit comprising: a front-pulse generating part for generating the front pulse; and a rear-pulse generating part for generating the rear pulse, wherein the front-pulse generating part is configured to receive a front start pulse and a series of first clock signals, the front-pulse generating part comprising: a first pull-up circuit for providing a first signal in a first state in response to the front start pulse a second pull-up circuit to at least maintain the first signal in the first state; and a first pull-down circuit for providing a second signal in response to the first signal, wherein the second signal is in a pulled-down state in reference to the reference voltage when the first signal is in the first state, and wherein the second pull-up circuit is further configured to receive the first clock signals in order to provide the front pulse in response to the first clock signals while the second signal is in the pulled-down state; and wherein the rear-pulse generating part is configured to receive a rear start pulse and a series of second clock signals, the rear-pulse generating part comprising: a first pull-up circuit for providing a first signal in a first state in response to the rear start pulse a second pull-up circuit to at least maintain the first signal in the first state; and a first pull-down circuit for providing a second signal in response to the first signal, wherein the second signal is in a-pulled down state in reference to the reference voltage when the first signal is in the first state, and wherein the second pull-up circuit is further configured to receive the second clock signals in order to provide the rear pulse in response to the second clock signals while the second signal is in the pulled down state, wherein the rear start pulse follows the front start pulse such as to separate the rear pulse from the front pulse and wherein the front start pulse has a first pulse length and the rear start pulse has a second pulse length greater than the first pulse length.
