Abstract

According to the invention, there is provided a low power analog FM transceiver for biotelemetry applications. The FM transmitter having a frequency chopper for increasing bandwidth of the input signal according to a given modulation index, a low pass Filter; a frequency modulator for performing frequency modulation of the filtered signal; and a non-linear high efficiency power-amplifier for amplifying the frequency modulated signal. The FM receiver comprises a low noise amplifier for amplifying the received frequency modulated signal to generate an amplified signal having a pre-estimated SNR lesser than a desired SNR of output signal of the FM receiver; a linear frequency demodulator for performing frequency demodulation of the signal of the pre-estimated SNR; and another frequency chopper for decreasing bandwidth of the frequency demodulated signal to obtain the output signal of bandwidth similar to bandwidth of the input signal.
