Significance of Electronic Noise (3) ± The "fidelity" of electronic systems is often determined by their SNR – Examples • Audio systems Imagers cameras Imagers, cameras • Wireless and wireline transceivers ± Electronic noise directly trades with power dissipation and speed In most circuits, low noise dictates large capacitors (and/or small R, large g m ), which means high power dissipation ± Noise has become increasingly important in modern technologies with reduced supply voltages – SNR ~ V signal 2 /V noise 2 ~ ( α V DD ) 2 /V noise 2 ± Designing a low-power, high-SNR circuit requires good understanding of electronic noise B. Murmann EE214 Winter 2010-11 – Chapter 1 7 Distortion v o v i Small-signal approximation ± All electronic circuits exhibit some level of nonlinear behavior The resulting waveform distortion is not captured in linearized small- The resulting waveform distortion is not captured in linearized small signal models ± The distortion analysis tools covered in EE214 will allow us to quantify the impact of nonlinearities on sinusoidal waveforms B.

Significance of Distortion ± For a single tone input, the nonlinear terms in a circuit’s transfer function primarily result in signal harmonics ± For a two-tone input, the nonlinear terms in a circuit’s transfer function result in so-called “intermodulation products” Example: Two interferer tones create an
