Temperature Analysis: Reference Circuits

This lecture covers the analysis of temperature-independent biasing circuits, focusing on the CTAT and PTAT references. It explains the concept of supply-independent biasing, the characteristics of negative-TC references, and the design of diode-referenced self-biasing circuits. The lecture also delves into the generation of PTAT and CTAT references, as well as the implementation of bandgap references in low-voltage ICs. The discussion extends to the use of bipolar structures in CMOS processes, particularly the vertical parasitic pnp bipolar configuration.
