INVESTIGATION OF A TUNNEL DIODE OSCILLATOR AS AN ANALOG TO DIGITAL CHARGE CONVERTER,
Abstract
A 10 ma gallium arsenide tunnel diode has been used an an oscillator. The oscillator power supply voltage is adjusted so that the diode is in its low voltage state and cannot oscillate. An amount of charge Q is introduced into the circuit and if this charge is great enough, the circuit oscillates for a short time. The charge Q is introduced in one of two ways; the capacitance is kept constant and the voltage is increased or the voltage is kept constant and the capacitance is varied. It was found that when the charge is introduced by keeping the voltage constant and varying the capacitance, a linear relationship exists between the charge Q and the number of oscillations. However, when the capacitance is constant and the voltage is varied, the circuit reaches a point where an increase in Q causes no increase in the number of oscillations. (Author)
