| 概要： |
- I will discuss low power LSI design featuring low power ADC design.
- Power break through often made new applications and markets,
such as watch-like cellular phone, handy digital camera, and on-board DVD in notePC.
Current and future big market must be the IoT systems.
- Logic circuit has progressed from fast but power hungry CML to CMOS
that doesn't consume any static power and no relation between speed and
consumed energy. Small capacitance and low voltage operation are the key.
- ADC plays an important role for all electrical systems,
however unlike logic circuits; accuracy, distortion, and noise should be considered.
Furthermore, these factors have tough tradeoff against low energy operation
and conventionally uses OPamps that need static current.
- CMOS technology that had been regarded as not suitable for ADC
application due to large mismatch, however conquered it by using
capacitance to realize S/H and to absorb mismatch voltage.
- Recent advanced ADC uses dynamic CMOS circuit and more aggressively
replaces conventional amplifier.
講演資料は英語ですが、講演は日本語で行われます。
この講演は、群馬大学での講義「集積回路システム工学」を兼ねています。
