Modulbeschreibung - Analogue Circuit Design
(Analoge Schaltungstechnik)

ECTS 3.0
Level advanced
Overview This course deals with all aspects that are necessary to understand and design transistor circuits of all kinds as they are used in continuous-time and discrete-time analog electronics.

  • Transistor physics
  • One-transistor amplifiers and current mirrors
  • Differential pairs
  • Simple OTA (Operational Transconductor Amplifier)
  • Complex OTAs: current-mirror OTA with gain enhancement, folded-cascode OTA
  • Miller effect
  • OpAmps (Operational Amplifiers) and Miller OpAmps
  • Switched-capacitor amplifiers with and without offset cancellation (auto-zero and correlated double sampling)
  • Stability criteria, non-linearity, CMR, PSR, SNDR, etc.
  • Bandgap and current references
  • Voltage regulators: stability, load change, ESR resistors of decoupling caps
Learning objectives The students gain an understanding of what element parameters can be changed by an IC designer and what parameters are given by an IC manufacturing process.

They are able to derive both the operating point and the small-signal parameters of transistors from given technology information and transistor dimensions, and they also understand the reverse calculation of transistor dimensions from transistor parameters.

They understand the connections between transistor parameters and the performance of current mirrors and amplifiers, and they can do calculations between transistor dimensions, transistor parameters, and amplifier performance parameters in both directions.

They can explain the fundamental differences between continuous-time and discrete-time amplifiers, and have a grasp of settling-time considerations.

They can use their knowledge to improve their understanding of off-the-shelf integrated circuits.

Finally, they can apply everything from astGL to integrated circuits.
