EEC 116 Lecture #5: CMOS Logic

Equivalent Inverter • CMOS gates: many paths to Vdd and Gnd – Multiple values for V M, V IL, V IH, etc – Different delays for each input combination • Equivalent inverter – Represent each gate as an inverter with appropriate device width – Include only transistors which are on or switching –Cacualelt V M, delays, etc using ...

VERILOG 6: DECODER DESIGN EXAMPLES

Decoder Design Using Predecoding •Example: 256-output (8 input bits) with predecode –Ex: take groups of 2 input bits •Four possibilities; activate one of four wires (use 2 INVs, 4 ANDs) –Wires along array: 22 * (8/2) = 4 groups of 4 = 16 (same as non-predecoded) –Each output uses a 4-input AND gate (much faster)

is very narrow. If the application calls for a black etch, consider using an oxidizer after engraving. Oxidizers are used most commonly if the aluminum has a protective coating (urethane, clear coat, clear anodized) covering the area that is not engraved. Deep metal engraving on aluminum can be done using multiple passes.
