Detectors- Kazan
Improvements:
- larger ground holes(viases)
- PD case to ground
- small capacitors to 1206 case
Shot noise and thermal noise
Shot noise accompanies a flow of electric current. Any resistor at any given temperature emits thermal noise. Amplification is a nonequilibrium process, and thus amplification involves noise sources other than thermal sources.[1]
