<p>A device and method for threshold voltage programming of an Ion Sensitive Field Effect Transistor (ISFET). This is of particular use in matching ISFETs in an array, which may be used in biological reaction monitoring. A circuit comprises an Ion Sensitive Field Effect Transistor (ISFET) having a floating gate (111) and two tunnelling inputs (Vt-, 148,149; Vt+, 145, 146) coupled by capacitors (Ct-, Ct+) to the floating gate for bidirectional electron tunnelling to program a charge on the floating gate.</p> |
