[Discuss] What's the most difficult topic in analog/mixed IC

[currentmirror2000]

What's the most difficult topic in analog/mixed IC you think? e.g., amplifier, voltage regulator, a/d d/a, pll, etc.

Any discuss is welcome!

I think Analog design is itself more difficult then digital design as you have to deal with several different parameters that interact with each other, while in digital, you have 1 or 0 and you're concerned not "how" the node will go to 0 or 1 but "when", that is to say you're concerned with the delay, also meanind the speed of your digital circuit. in the analog one you have to deal with not only when but also how question and accuracy and stability and robustness and noise etc..
Looking at analog design, i think the topics that you had more experience on is easier for you than the ones you're not familiar with. but it doesn't mean one topic is more difficult than another. maybe it might be more time consuming to get to know than another..

In 2-3 years a SOC with 60GHz radio with adaptive beam antennas, two stage conversion, 500MHz bandwith IF, 10bit 1GS A/D, 1GBit FFT processing have to put on a 90-130nm RFCMOS or SiGeBiCMOS single die.

In the group of Analog Device : Operational Amplifier is the most chalenging when it requires high gain and fast.

In AMS subdivision

1. Data Conversion (ADC) : Pipeline architechture in high speed and high resolution
2. RFIC : this part of analog is very sensitive because the input is microwave not even an analog signal

This is only to my limited experience....glad to hear more opinion
