Patent ID: 7782115

Claim:
A switching circuit system, comprising: an input module, operable to receive a two-level input signal representing input information, and to generate a first switching voltage signal and a second switching voltage signal as a function of the input signal; a current signal generator module, comprising: a first current switching device, operable to generate a first switching current signal as a function of the first switching voltage signal; and a second current switching device, operable to generate a second switching current signal as a function of the second switching voltage signal; a first precharging device, coupled with the first current switching device and the second current switching device, and operable to build up a charge reserve when the second switching voltage signal is HIGH, and to dump at least a portion of the charge reserve into the first current switching device when the first switching voltage signal is HIGH; a second precharging device, coupled with the first current switching device and the second current switching device, and operable to build up a charge reserve when the first switching voltage signal is HIGH, and to dump at least a portion of the charge reserve into the second current switching device when the second switching voltage signal is HIGH; a voltage signal generator module, operable to generate a first voltage response as a function of the first switching current signal and to generate a second voltage response as a function of the second switching current signal; and a latching module, operable to generate a two-level latched signal as a function of the first voltage response and the second voltage response, such that the latched signal substantially preserves the input information represented by the input signal.
