Cascading Amp Stages For Higher Gain
One goal of cascading amplifier stages is to achieve higher levels of gain without sacrificing gain flatness across the design bandwidth of interest.
Achieving High Gain Over Broad Bandwidths
By computer optimizing key circuit elements and applying negative feedback, level transistor gain can be achieved over very broad bandwidths.
Approach Yields Low-Noise Amplifiers
The available gain method permits amplifier designers to achieve moderate gain while minimizing noise figure at a given target frequency.
Applying The Operating Gain Design Approach
The operating-gain design method gain provides higher levels of gain than earlier design approaches, although it may not guarantee unconditional stability.
Method Simultaneously Matches Inputs and Outputs
For the case of an unconditionally stable transistor, it is possible to simultaneously match the devices input and output ports to the load and source.
Approach Increases Amplifier Gain
The unilateral gain design technique can be applied to tune a transistors input and output circuitry for more gain.
Ensure Stability In Amplifier Designs
Knowledge of stability circles and S-parameters can help to develop input and output matching circuits that deliver stable amplifier performance at a desired frequency.
Applying S-Parameters To Amplifier Design
This opening installment of an eight-part design series explains the concept of S-parameters and how they can be used to create basic transistor bias circuitry.
