Integrated Wideband RF Tracking Filter for RF Front End with Parallel Band Switched Tuned Amplifiers |
摘要 |
A wideband RF tracking filter having a set of parallel tuned resonator amplifier stages with a de-Q resistor for each subband is disclosed. The resonant amplifier contains programmable tuned LC tank impedance and an array of parallel voltage to current converters (V2I) for each subband. The de-Q resistor together with the array of V2I converters provides a flat gain over each subband and each of the other subbands covering different frequencies.
