1. A sensor device, comprising:
- a data source including an analog sensor array on a substrate;
peripheral circuitry coupled to the sensor array configured to produce a plurality of streams of digital data;
a plurality of transmitters on the substrate configured to receive corresponding streams of data from the data source in parallel;
a temperature sensor configured to sense a temperature that correlates with the temperature of the sensor array;
a sequencer configured to operate the data source, the peripheral circuitry and the plurality of transmitters to sample frames of data at a frame rate according an active mode and an idle mode, wherein the sequencer operates in the active mode for a first number of frames in a time interval overlapping with a flow of reactant solution and in the idle mode for a second number of frames in a time interval overlapping with an immediately following flow of wash solution; and
a controller coupled with the temperature sensor and the sequencer configured to adjust the first and second number of frames in response to the sensed temperature.

Abstract
A sensor device includes a sensor array and a flow cell in fluid communication with the sensor array. Bias circuitry apply bias arrangements to the sensor array to produce sensor data. Peripheral circuitry coupled to the bias circuitry produces streams of data from the sensor array, the peripheral circuitry having an active mode and an idle mode. Logic to switch the peripheral circuitry between the active mode and the idle mode to control power consumption is provided. A temperature sensor may be included, and the logic can operate with feedback to switch between the active mode and the idle mode to maintain the temperature within an operating range.
