Abstract
An analog floating gate circuit (--) includes a first sense transistor (), a first storage capacitor (), and first () and second (A,) tunneling regions. Various portions of a first floating gate conductor () form a floating gate of the first sense transistor, a floating first plate of the first storage capacitor (), a floating first plate of the first tunneling region, and a floating first plate of the second tunneling region, respectively. A second plate of the first storage capacitor is coupled to a first reference voltage (V, GND), and a second plate of the second tunneling region is coupled to a second reference voltage (V/GND). Compensation circuitry (--) is coupled to the first floating gate conductor, for compensating loss of trapped charge from the first floating gate conductor.
