Abstract :
A remotely controllable and programmable multi-channel 72-225MHz miniature FM receiver for hearing aids draws 2.2mA from a 0.9V-1.6V supply. The receiver achieves an SNR of 43dB and a sensitivity of -103dBm for an audio bandwidth of 7.5kHz. The IC is realized in 0.25μm CMOS and occupies 22.7mm2.
