Biosensor with multi-channel A/D conversion and a method thereof
First Claim
1. A biosensor with multi-channel A/D conversion, comprising:
- a chip generating a time-dependent analog signal in response to a content of a specific component of a specimen provided on said chip;
a multi-channel A/D converter with multiple channels each of which simultaneously receiving the time-dependent analog signal in each sampling interval in order that said multi-channel A/D converter converts the time-dependent analog signal to a set of digital signals; and
a microprocessor receiving the sets of digital signals in a period of sampling time and determining the content of the specific component based on the sets of digital signals.

Abstract
A biosensor with multi-channel A/D conversion and a method thereof are provided. The present biosensor includes a chip generating a time-dependent analog signal in response to a content of a specific component of a specimen provided thereon, a multi-channel A/D converter, and a microprocessor. The multi-channel A/D converter has multiple channels simultaneously receiving the time-dependent analog signal in each sampling interval to convert the time-dependent analog signal to a set of digital signals. The microprocessor receives the sets of digital signals in a period of sampling time and determines the content of the specific component based on the sets of digital signals. The present biosensor provides a multi-channel A/D conversion for the time-dependent analog signal to improve the resolution of the determination of the content of the specific component.
