System for reducing noise in a chemical sensor array

摘要

A system including a power supply and a clock circuitry to generate a plurality of clock signals. Each clock signal is synchronous with a primary clock signal. First, second, and third clock signals of the plurality of clock signals are asynchronous to each other. The system further includes a plurality of switches. Each switch of the plurality of switches is communicatively coupled to the power supply and the clock circuitry. A first switch of the plurality of switches receives the first clock signal, a second switch of the plurality of switches receives the second clock signal, and a third switch of the plurality of switches receives the third clock signal.

1. A system comprising:
a first analog-to-digital converter to receive an output signal from a sensor array; a first switcher to power the sensor array and the first analog-to-digital converter; and a clock generator to generate a plurality of clock signals that are synchronous with a primary clock signal, the clock generator provides a first clock signal of the plurality to the first analog-to-digital converter and provides a second clock signal of the plurality to the first switcher, the first clock signal is asynchronous with the second clock signal.
