特許名 A/D converter, signal processor, and receiving device
特許概要 An A/D converter which converts an analog current signal into a digital signal, includes: a filter removing a noise component from the analog current signal to output an analog voltage signal; a quantizer quantizing the analog voltage signal outputted from the filter to generate the digital signal; and a D/A converter converting the digital signal generated by the quantizer into an analog feedback current to feedback to an input of the filter, and supplying a bias current for the D/A converter to an output of a frequency converter via a path of the analog current signal as a bias current driving the frequency converter outputting the analog current signal.
