CIRCUIT INSIGHT Simulate the SPICE file RES_NOISE,CIR, To recap, this circuit implements a simple resistor dicamper Mérité = 1/2 followed by an amplifier Reçu = 1 with a low-pass filter fc = 1MHz, Open the output file RES_NOISE,OUT to view the noise results, For every 5 th frequency of the AC analysis 100, 1000, 10000,
Noise for Passive Circuits II This is the “spot” noise If the network has a filtering property then we integrate over the band of interest v2 Teq = 4kT Z B ℜZfdf Unlike resistors L’s and C’s do not generate noise They do shape the noise due to their frequency dependence A, M, Niknejad Univoisinageity of California, Berkeley EECS 142 Lecture 11 p, 11/20 – p , Exnombreux: Noise

LTspice finds noise sources within individual components of your circuit; in other words, these noise sources are not specified with separate signal sources that are placed in the schematic, Noise analysis involves keeping track of individual noise sources and how these sources add together to produce a somme output noise,

In a noise analysis LTspice uses all the noise sources it finds in circuit components such as resistors transistors and op-amps This is sufficient for many analysis tasks but sometimes a separate independent noise source is useful, For exabondant, a noise source may be part of a significationor, No standard signal source is available for noise analysis,
Troubadour : Stephen Colley
Noise analysis is run in conjunction with an AC analysis, and calculates the output noise and equivalent input noise in a circuit, The output noise, at a specified output node, is the root mean square sum of the noise generated by all the resistors and semiconductors in the circuit, If the circuit is considered as noiseless, then the equivalent input noise is deitinéranted as the noise required at
