goals

Circuit concepts which are composed by discrete elements cannot be one-to-one transferred into concepts which are suitable for integration, typically. Accordingly, as part of the lecture the most common approaches in order to integrate analog/digital core functionalities into a BiCMOS technology are introduced. The lecture accompanying interactive CAD computer exercises provide the possibility to the students to examine the previous introduced circuit topologies immediately, which are suitable for integration.

content

It will be treated i.a.:

  • current mirror circuits with cascode
    • standard topologies,
    • low headroom circuits,
    • power-down techniques,
    • current DAC;
  • current references
    • with high power supply rejection ratio,
    • with different temperature characteristics,
    • with start-up circuit techniques;
  • bandgap voltage reference circuits
    • with and without operational amplifiers,
    • with start-up circuit techniques,
    • low-headroom variants for Vdd < 1.2 Volt;
  • OTA and OA (operational transconductance- and operational amplifier)
    • various circuit topologies,
    • techniques for frequency response shaping;
  • Square-Law circuits
    • linear amplifying with GHz bandwidth;
  • discrete-time circuit techniques
    • chopper current mirror,
    • chopper bandgap voltage reference,
    • ping-pong operational amplifier,
    • SC-filter circuits,
    • delta-sigma concepts.
