摘要： Methods and systems for processing signals wherein a plurality of signals are received at the inputs of a plurality of transconductance circuits which convert the signals into their corresponding current signals. The current signals are then multiplexed into an internal signal. The internal signal is further filtered and transmitted to an output. The transconductance circuits may be programmable in order to adjust and optimize their transconductance. Any of the input signals may result from a downconverting and filtering process.

摘要： An N-path filter with each path forming a different filter. A signal insertion block is provided at the start of the circuit and, in one embodiment, multiple memory capacitors are coupled to the signal insertion block. A bank of sequential rotating capacitors are provided along with a bank of switches. By activating selected switches, any of the memory capacitors can be coupled to selected rotating capacitors. A different filter subcircuit is formed by coupling each memory capacitor to different rotating capacitors as this creates a different signal path. By timing the switching of the rotating capacitors, signals from previous outputs can be inserted into the circuit. At the output end of the circuit, the output of the different filter subcircuits is put together into an output for the whole circuit.

摘要： Circuits and methods related to charge domain filters. A time varying current distributor produces multiple time varying current outputs which are received by filter elements. The outputs of the filter elements are received by a selector component which selects one of the filter outputs for its output. The time varying current distributor has multiple transconductance circuits, each of which produces time varying currents which are proportional to a distributor input. The transconductance circuits are composed of transconductance sub-circuits, each of which produces time varying currents, each of which is offset from other time varying currents by a predetermined time interval.
