Detection and analysis of biological and biochemical signals via compact sensor systems require low-power and compact analog-to-digital converter (ADC) systems. Here we present a highly sensitive flash current-mode ADC (IADC) design with resolution down to 15pA. The IADC's small-size and low-power capabilities allow integration for stand-alone biological or chemical microsensor applications.
