摘要： An electronic circuit includes a floating gate transistor with a floating gate capacitor. The floating gate transistor can be programmed to be in an ON or an OFF state by charging the floating gate capacitor. The circuit further includes a deactivation capacitor adapted to store a charge sufficient for deactivating the floating gate transistor temporarily. The deactivation capacitor is connectable in series to the floating gate capacitor. A method for deactivating a floating gate transistor temporarily is provided, wherein the floating gate transistor includes a floating gate capacitor. A deactivation capacitor is charged with a charge sufficient for changing the state of the floating gate transistor temporarily. The deactivation capacitor is connected in series to the floating gate capacitor for deactivating the floating gate transistor.

摘要： An ASK demodulator for use in an RFID transponder having a limiter circuit associated with the antenna circuit and converting the ASK antenna field strength modulation into an ASK limiter current modulation by limiting the antenna voltage to a fixed value and thereby causing the limiter current to be substantially proportional to the ASK antenna field strength, and a current discriminator circuit that discriminates the ASK limiter current modulation. By converting the field strength modulation into a proportional limiter current and discriminating that limiter current, a linear relationship and a stable demodulator sensitivity are achieved. The current discrimination can be made accurately under low-voltage conditions.
