Design of an Instrumentation Amplifier
www.egr.msu.eduIntroduction An instrumentation amplifier is an integrated circuit (IC) that is used to amplify a signal. This type of amplifier is in the differential amplifier family because it amplifies the difference between two inputs. The importance of an instrumentation amplifier is that it can reduce unwanted noise that is picked up by the circuit.

www.firstwatt.comAMP CAMP AMP #1 by Nelson Pass Introduction Do-It-Yourself audio is a great activity. Many major audio components are easily constructed and made to perform as well or better than what we see in the stores and at considerable savings. The process is educational and therapeutic and there are few greater satisfactions

Due to the resultant smaller VBE of the 8× area Q2, R2 in series with Q2 drops the ΔVBE voltage, while R1 (due to the current relationships) drops a PTAT voltage V1: 1 VBE R2 R1 V 2. Eq. 1 . The bandgap cell reference voltage VZ appears at the base of Q1, and is the sum of VBE (Q1) and V1, or 1.205 V, the bandgap voltage: Z =V V
