摘要： An electronic circuit includes an analog to digital converter (ADC) and a noise coupling filter. The ADC generates a digital output signal based on a first analog signal and a second analog signal. The noise coupling filter generates the second analog signal to be fed back for an input to the ADC, based on a first quantization error signal associated with converting the first analog signal to the digital output signal. The noise coupling filter performs noise shaping on a digital error signal derived from the quantization error signal and generates the second analog signal from a result of the noise shaping, using a clock in the digital domain.

摘要： An electrode assembly for measuring bio-signals includes a body, a fastening member extending from the body and provided on one side of the body, the fastening member including a spring groove formed therein and an aperture penetrating therethrough, and a spring inserted into the spring groove. The aperture receives a fastening stud of a patch which is supplied from outside. The spring compresses the fastening stud received in the aperture such that the fastening member fixes the fastening stud thereto.
