EE 214 Lecture 22 (HO#30)B. Murmann2Overview•Reading–4.3.5 (Differential Pair with Current Mirror Load)–6.3.3 (Systematic Offset in Two-Stage Amplifier)–Chapter 5 (Output Stages)•Introduction–This lecture concludes our discussion of amplifier implementations by looking at a number of missing bits and pieces. First, we will discuss subtleties of OTA implementations that use a single ended output. While rarely used in the signal path of high performanceintegrated circuits, OTAs with single ended outputs can be useful as auxiliary amplifiers in biasing circuits. Finally, we will take brief look at output stages that are suitable for driving resistive loads. While most on-chip loads tend to be capacitive in nature, low impedance drivers are often needed when interfacing to off-chip components and wire lines.
