EM Modeling and Circuit Simulation Lead to a Solution to Amplifier Oscillations

A procedure to resolve an oscillation issue in a two-stage broadband amplifier is presented based on electromagnetic (EM) modeling and circuit simulations. It is revealed that an additional inductive element of a value larger than 0.5 nH in the inter-s...
The design of either a power amplifier, low noise amplifier, narrow band amplifier or wideband amplifier has been a challenging task for the microwave engineer. Stability is the most important issue the engineer has to face. 1 It can haunt a designer, starting from the design phase, through the...
