<p>A signal processing system that converts an analog data signal to a digital data signal comprises a current-input/current-output circuit as a filter circuit (FIL), and a current-input circuit as an analog-to-digital converter (ADC). The front stage of the filter circuit includes a voltage-to-current converting circuit or voltage-input/current-output amplifier (VGA) to convert received analog input signals to electric current.</p> |
