6.002 Demo# 10 ( Load Set up demo#10PG.set) : (Load Set up Demo#10AA.set) I DS vs. V DS Load Line Agarwal/Fall 00 Lectures 10 and 11 Purpose: In this demo, a picture of the MOSFET amplifier behavior is presented by displaying a load line over a set of (premade) MOSFET i-v curves. The load line crosses the family of MOSFET curves in the saturation region, and ends in the ohmic region. By using music as the amplifier input, and by sending the output to a speaker, distortion can be heard when the signal is outside the saturation region. This is seen on the scope as the (partial) load line being in the saturation region (no distortion), in the ohmic region (distortion), or near the cutoff region (distortion/low volume). As a fun and interesting aside, we can show that classical music suffers much more perceptually than does, say, heavy metal. Steps: 1. Having previously aligned the load line with the stored MOSFET curves, use the sinusoid input to show the entire load line. 2.
