Title: The Innovations of Daniel E Skooglund
Introduction
Daniel E Skooglund is a notable inventor based in Wappingers Falls, NY. He has made significant contributions to the field of electronics, particularly in the development of advanced circuit designs. With a total of 4 patents to his name, Skooglund's work has had a meaningful impact on the industry.
Latest Patents
One of Skooglund's latest patents is for an active, low Vsd, field effect transistor current source. This innovative circuit operates advantageously in the linear region of a field-effect transistor (FET) and minimizes any voltage drop at its output node that is not load related. The design allows for dynamic measurement of output current without introducing elements that affect the voltage drop across the FET. The current source includes a pass device with feedback control, ensuring a constant current is maintained regardless of the load at the output terminal. Additionally, the operation of the pass device is mirrored by a second pass device that has physical dimensions only a fraction of those of the first. A high input impedance differential amplifier drives the respective outputs of both pass devices, forcing the mirror pass device to match the voltage of the first pass device.
Another significant patent involves a driver circuit for testing bi-directional transceiver semiconductors. This driver circuit is designed to test bi-directional transceiver semiconductor products efficiently, using a minimum of time and product accessing pins. It features a pair of controllable amplitude current sources whose output currents can be selectively switched into or partially away from the commonly connected emitters of a current switch. Energized by a variable voltage source, the current switch produces the output test voltage.
