The extremely fast ionization process in semiconductors offers a means of generating pulses that have sub -nanosecond rise times and high peak powers. There are several important applications of these pulses which require the duration of the generated pulse to be variable. This thesis investigates three methods of producing variable...
The design of a preamplifier for use with a piezoelectric transducer is generally approached from the point of view that an extremely high input impedance is required to obtain low frequency response. However, piezoelectric transducers are essentially charge generators and this fact may be utilized in designing preamplifiers to be...
Conventional bi-polar transistors are inherently low input
impedance devices. Transistor amplifiers have been designed
which will present high input impedance, but the frequency response
is limited to low frequencies, hundreds of kilocycles.
This thesis investigates both field effect transistors and
positive feedback as applied to high input impedance wide band...
The selective masking effect of a thermally grown layer of silicon
dioxide has been widely utilized as a technique for controlling the
geometry and impurity concentration in semi-conductor device technology.
It is also recognized that the passivation of the silicon surface
by the vitreous silicon dioxide envelope protects the underlying...
This thesis is an investigation of the characteristics of transistor-coupled logic using both theoretic and experimental methods. The steady state and transient behavior of the transistor are first investigated, especially as applied to the common emitter configuration. A number of references giving further information are cited.
Next, the characteristics of...
