Abstract
A transistor amplifier has an integral resistance-capacitance negative feedback network in order to stabilize it and allow a broadband impedance match. To minimize transmission line effects and phase shifts, the capacitor is formed using a control electrode pad as one capacitor plate and the control electrode has integral fingers. The resistor can be of the floating gate type for ease of construction. The transistor can be an FET.
Claims9
An amplifier comprising:
- a semi-insulating substrate;
- a conducting mesa overlying said substrate;
- a transistor disposed on said substrate and having a control electrode including a pad, a grounded common electrode and at least one output electrode;
- a capacitor comprising said control electrode pad as a first plate, a dielectric overlying said control electrode pad, and a second plate overlying said dielectric;
- and
- at least one floating gate resistor connecting said output electrode and said second plate and comprising at least one conducting strip disposed on said mesa and forming a Schottky barrier therewith.
