Abstract

THE CAPACITANCE OF A SMOOTHING CAPACITOR IS REDUCED, AND THE SIZE OF AN IC CHIP IS MINIMIZED. A SERIES TRANSISTOR IS PROVIDED ON THE OUTPUT SIDE OF A DIODE WHICH RECTIFIES THE OUTPUT VOLTAGE OF AN ANTENNA, AND THE SMOOTHING CAPACITOR IS CONNECTED TO THE BASE OF THE SERIES TRANSISTOR. IF THE CURRENT GAIN OF THE SERIES TRANSISTOR (T) IS ?, THEN THE APPARENT CAPACITANCE OF THE SMOOTHING CAPACITOR (C2) IS MULTIPLIED BY ?.
