Advanced Analog Integrated Circuits Why is analog design challenging? Digital circuits deal primarily with speed power tradeoff. Analog circuits deal with multi-dimensional tradeoff of speed, power, gain, precision, supply, … Due to speed and precision requirements, analog circuits are much more sensitive to noise, crosstalk, and other interferers. Why is analog design challenging? (cont.) Analog circuits are much more sensitive to second-order device effects High performance analog circuit design can rarely be automated - typically require hand-crafted design and layout Modeling and simulation of analog circuits is still problematic, requiring experience and instruction Why is analog design challenging? (cont.) Economic forces is pushing the integration of analog and digital functions onto a single substrate Many levels of abstraction are required
