ABSTRACT:
A precharge circuit that initializes an electronic filter to a middle voltage level of an operational voltage includes a filter isolation device, a filter communication device, and an initializing device. The filter isolation device isolates the electronic filter from electronic circuits connected to an input and an output of the electronic filter to segregate the electronic filter from the electronic circuits connected to the input and the output of the electronic filter during a precharge time. The filter communication device allows communication between the precharge circuit and the electronic filter for initializing the charge state during the precharge time. The initializing device provides an initializing signal to the charge state of the electronic filter during the precharge time. The precharge circuit further has a biasing device in communication with the initializing device to provide a mid level control signal providing a reference level of the charge state.
