This is a classic FM amplifier IF amplification stage configuration. The circuit is from a 1980s documentation. CN is the neutralizing capacitor.
This 80's circuit can be implemented with modern equivalent FETs with lower on resistance. The...
This circuit, which uses only common transistors, was obtained from a 1988 publication, but can be...
This circuit that also has a Power On reset was obtained from a 2005 Linear Technology manual. The...
