发明名称 Analog floating gate charge loss compensation circuitry and method
摘要 An analog floating gate circuit (10-3, 10-4) includes a first sense transistor (21, 3), a first storage capacitor (20, 5), and first (24, 4) and second (31A, 42) tunneling regions. Various portions of a first floating gate conductor (12, 2) form a floating gate of the first sense transistor, a floating first plate of the first storage capacitor (20, 5), 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 (VREF, GND), and a second plate of the second tunneling region is coupled to a second reference voltage (VPROG/GND). Compensation circuitry (44-1, 44-2) is coupled to the first floating gate conductor, for compensating loss of trapped charge from the first floating gate conductor.
