HIGH-SPEED MOLECULAR DIAGNOSTICS

摘要

A system for high-speed molecular diagnostics includes a self-resetting continuous- time integrator configured to integrate an input current on one of a plurality of integration capacitors to generate an integrated voltage. A self-resetting continuous-time differentiator is configured to differentiate the integrated voltage on one of a plurality of differentiating capacitors to generate an output voltage proportional to the input current. A fixed-threshold window comparator is configured to reset one of the plurality of integration capacitors, reset one of the plurality of differentiating capacitors, open a second one of the plurality of integration capacitors and open a second one of the plurality of differentiating capacitors in response to the integrated voltage exceeding a voltage range.
