Title: John J Ennis: Innovator in Gallium Arsenide Technology
Introduction
John J Ennis is a notable inventor based in Corona, California. He has made significant contributions to the field of electronics, particularly in the development of gallium arsenide technology. With a total of 2 patents to his name, Ennis has demonstrated his expertise and innovative spirit in the industry.
Latest Patents
Ennis's latest patents include the GaAs driver circuit and the tri-state type driver circuit. The GaAs driver circuit comprises a gallium arsenide driver with float capability for logic high and logic low signals. It includes logic means for receiving an input signal and providing logic high and low signals. Level shift means responsive to the high and low signals downshift the voltage levels. Common gate means responsive to the downshifted signal voltage levels amplify these signals, while output source-follower means provide output signals to a pad. The tri-state type driver circuit features an FET complementary pair that provides the output to a data line. A data input line is coupled to the gate of the P-FET via an OR gate configuration and to the gate of the N-FET via an AND gate configuration. The output of each gate configuration is cross-connected to an input of the other. This design ensures that both FETs are not ON at the same time, preventing undesirable power flow.
