发明名称 Baseband analog circuit with improved noise characteristics
摘要 A baseband analog circuit includes a demodulator to demodulate a received signal and to output a baseband analog signal, a low-pass filter to filter the demodulated baseband analog signal, and an impedance converter, provided between the demodulator and the low-pass filter, having lower output impedance than the output impedance of the demodulator.
