摘要：
A differential pair sensing circuit (300) includes control gates (306, 316) for separately programming a reference transistor (350) and a chemically-sensitive transistor (351) to a desired threshold voltage Vt to eliminate the mismatch between the transistors in order to increase the sensitivity and/or accuracy of the sensing circuit without increasing the circuit size.
