DESCRIPTION
The IC The input stage meets two main functions. First, it provides a suitable bias voltage for the PIN diode. Secondly, the pulsed photo current signals are transformed into a voltage by a special circuit which is optimized for low noise application. After amplification by a Controlled Gain Amplifier (CGA), the signals pass a tuned integrated narrow bandpass filter with a center frequency f 0 equivalent to the chosen carrier frequency of the input signal. The demodulator is used to convert the input burst signal to a digital envelope output pulse and to evaluate the signal information quality, i.e., unwanted pulses will be suppressed at the output pin.
