Learning Objectives

The course is aimed to develop advanced design skills in analog and mixed-signal integrated circuits

Detailed Course Content

  1. From Electronics to Micro and Nano electronics. VLSI technologies. Asics and design steps.
  2. Operational amplifiers and applications: instrumentation amplifier, logarithmic amplifier. Effect of finite gain and bandwidth. Noise and distortion. Op Amps architectures. Output stages. The uA741. 3. Operational Transconductance Amplifiers (OTAs). Miller OTAs (class A and AB). Folded Cascode OTA. Telescopic OTA etc. Low voltage solutions. Multistage OTAs and frequency compesnation schemes. Fully differential architectures and common mode control schemes.
  3. Comparators. Autozeroed comparators Schmitt Triggers.
  4. Filters. Active and passive filters, continuous time and discrete time solutions. First order and second order filters implmented in RLC, Active-RC, Switched-Capacitor, Gm-C and MOSFET-C approaches. Biqudratic cells (Thow-Thomas, Sallen-Key, Ackerberg-Mossberg, Delyannis-Friend). High-order filters. Gyrators. Automatic tuning for Gm-C filters.
  5. A/D e D/A converters. Performance and design specifications. Sample and Hold circuits. A/D examples: full flash, two step flash, time interleaved, successive approximation, ramp. D/A examples: current-steering (binary, thermometric, segmented), resistor-string, capacitor-string, ramp.
  6. Computer Aided Design Tools for microelectronics.
