摘要： A preselect circuit maintains the dynamic range of a received RF input signal during bandpass filtering of the received RF input signal. The preselect circuit includes a Q-deficient passive bandpass filter for coupling to an antenna to receive a received RF input signal. The preselect circuit further includes a Q-enhancement circuit coupled to the Q-deficient passive bandpass filter, wherein the Q-enhancement circuit increases a Q-value of the Q-deficient passive bandpass filter by compensating for resistive inductive losses in the bandpass filter.

摘要： A filter circuit enhances a deficient Q-value in a filter stage and buffers the filter stage from subsequent filter stages using a common active device. A filter circuit includes a first buffered filtering stage including a first Q-deficient filter stage to receive an input signal and a first Q-enhancement buffer stage. The first Q-enhancement buffer stage is coupled to the first Q-deficient filter stage, wherein the first Q-enhancement buffer stage includes a single active device to increase a Q-value of the first Q-deficient filter stage and isolate the first Q-deficient filter stage from any subsequent filter stage. A filtering method includes filtering an input signal in a first Q-deficient filter stage and enhancing a deficient Q-value of the first Q-deficient filter stage with an active device. The method further includes buffering the first Q-deficient filter stage from any subsequent filter stage with the active device.
