When working with real-world signals, designers often face the significant challenge of picking out a small signal from a large and varying common mode voltage. An ideal op amp would reject the common ...

The three circuit coefficients, T i+, T i-, and A 0 are part of the one-op-amp diff-amp model as developed in Part 1 of this article. By substituting for v + and v – in the v O equation and ...

A subject rarely found in circuit design textbooks is the matter of nonlinear junction capacitance, especially reverse-bias junction capacitance, also called depletion capacitance. When it is ...
