The circuit techniques used for noise reduction are correlated double sampling (CDS) and chopper stabilization (CHS) [3-13]. Phase noise can be estimated by a simplified version of Leeson’s equation: 2 10 2 0 sig u2 kTF log PQ ω ω ⎡ ⎛⎞ ⎤ ⎢ ⎜⎟⎥ ⎢ ⎝⎠Δ ⎥ ⎣ ⎦ 2 sig res BIAS p (1) This is a noise power (single sideband) to carrier power ratio …Use of negative feedback to improve noise figure 5.

IV. 49 REFERENCES 12. Broadband low noise amplifier design methodology. This is low noise tone control circuit using 4558 or easy make with one PCB layout board, can adjust bass treble mid volume,also use to microphone. An A low-noise amplifier (LNA) is an electronic amplifier that amplifies a very low-power signal without significantly degrading its signal-to-noise ratio. Every discrete or integrated LNA will have a printed circuit board layout on …Thermal noise power is also proportional to resistance so a low value resistance helps to reduce noise, although sometimes you need a high resistance so that is not always practical. wikipedia.
