Abstract
Official abstract text for this publication.
An oversampling A/D converter includes a first filter including a first resistive element, a first capacitive element, a second resistive element, an operational amplifier, and a second capacitive element; a second filter receiving an output of the first filter; a third filter including a third resistive element, a third capacitive element, and a fourth resistive element; a quantizer receiving an output of the third filter and generating a digital signal; and a D/A converter converting the digital signal to an analog current signal. The D/A converter inputs the generated analog current signal to an inverting input terminal of the operational amplifier.
First claim
Opening claim text (preview).
What is claimed is: 1. An oversampling A/D converter configured to perform digital conversion of an input signal, the oversampling A/D converter comprising: a first filter configured to receive the input signal and a first analog signal and to output a first output signal, a continuous-time filter configured to receive the first output signal and to output a second output signal, a second filter configured to receive the input signal and the second output signal and to output…
