Wideband Amplifier - A simplified explanation of the abstract

This abstract first appeared for US patent application 17824802 titled 'Wideband Amplifier

Simplified Explanation

The patent application describes a wideband amplifier that includes input and output matching networks.

• The input matching network matches the transconductor stage to an input impedance, while the output matching network matches the transconductor stage to an output impedance.
• Both the input and output matching networks consist of parallel LC tank circuits arranged in parallel with series LC tank circuits.
• The tank circuit arrangements allow the input and output matching networks to be resonant at three different frequencies: a first frequency, a midrange frequency higher than the first frequency, and a second frequency higher than the midrange frequency.
• This configuration enables the wideband amplifier to provide wideband matching, meaning it can effectively match a wide range of frequencies.

Original Abstract Submitted

A wideband amplifier includes an input matching network for matching a transconductor stage to an input impedance and includes an output matching network for matching the transconductor stage to an output impedance. Both the input and output matching networks each includes a parallel LC tank circuit arranged in parallel with a series LC tank circuit. The tank circuit arrangements configure the input and output matching networks to be resonant at a first frequency, a midrange frequency that is greater than the first frequency, and a second frequency that is greater than the midrange frequency to provide wideband matching.
