These proteins are also part of the immune system (immunoglobulins), help blood to clot (clotting factors), maintain pH balance, and are enzymes involved in chemical reactions throughout the body. Electrolytes are another large category of substances dissolved in plasma. They include:
An ideal op amp has infinite gain (), infinite input resistance ( ), and zero output resistance (). You should use these two assumptions to analyze the op amp circuits covered in the assignments below.
Input bias currents and input offset[edit] Practical operational amplifiers draw a small current from each of their inputs due to bias requirements (in the case of bipolar junction transistor-based inputs) or leakage (in the case of MOSFET-based inputs).
