3 Noise EE C45: Introduction to MEMS Design Lecture 7 C. Nguyen 1/8/08 3
4 Noise Noise: Random fluctuation of a given parameter I(t) In addition, a noise waveform has a zero average value Avg. value (e.g. could be DC current) I D I(t) t We can t handle noise at instantaneous times But we can handle some of the averaged effects of random fluctuations by giving noise a power spectral density representation Thus, represent noise by its mean-square value: Let i ( t ) = I ( t ) I D Then i 1 = ( I I ) = D lim I T T T 0 I D dt EE C45: Introduction to MEMS Design Lecture 7 C. Nguyen 1/8/08 4
5 Noise Spectral Density We can plot the spectral density of this mean-square value: i Δf [units /Hz] One-sided spectral density used in circuits measured by spectrum analyzers Two-sided spectral density (1/ the one-sided) d) Often used in systems courses i = integrated mean-square noise spectral density over all frequencies (area under the curve) EE C45: Introduction to MEMS Design Lecture 7 C.

EE C45: Introduction to MEMS Design Lecture 7 C. Nguyen 1/8/08 6 i ω
7 Handling Noise Deterministically Can do this for noise in a tiny bandwidth (e.g., 1 Hz) S n v n n 1 = S1 ( f Δf ω ο B ( jω) ) ω Can approximate this v = S ( f ) B v n 1 S S o i 1 ( ω ο ω ω o ω [This is actually the principle by which oscillators work oscillators are just noise going through a tiny bandwidth filter] B by a sinusoidal voltage generator (especially for small B, say 1 Hz) v o τ ~ (t) 1 B A cosω t Why? Neither the amplitude nor the phase of a signal can change appreciably within a time period 1/B. EE C45: Introduction to MEMS Design Lecture 7 C. Nguyen 1/8/08 7 o t
