Circuits By Roy Choudhary Fourth Edition Top — Linear Integrated

Analog fundamentals do not age. The concept of virtual ground, CMRR (Common Mode Rejection Ratio), and slew rate remain unchanged in modern ICs. If you understand Roy Choudhary’s analysis of a 741, you can design with an OPA277 (a modern precision op-amp) effortlessly.
