1. What is an instrumentation amplifier and what is it mainly used for?
An instrumentation amplifier is a high-precision amplifier designed to amplify low-level differential signals with high input impedance and high common mode rejection ratio (CMRR), and is commonly used in scenarios such as medical equipment, sensor signal processing, and industrial measurements.
-
2. What is Common Mode Rejection Ratio (CMRR) and why is it important for instrumentation amplifiers?
CMRR indicates an instrumentation amplifier's ability to suppress common mode signals, with higher values being better. A high CMRR is especially important in noisy environments to ensure that the amplifier primarily amplifies differential signals and is not affected by common mode interference.
-
3. How are operational amplifiers used in filter circuits?
Operational amplifiers can be used to build a variety of active filter circuits, including low-pass, high-pass, band-pass, and band-reject filters, which are commonly used for noise removal and signal conditioning in signal processing.
-
4. How do buffer amplifiers improve the signal integrity of a system?
Buffer amplifiers ensure distortion-free transmission of signals from source to load by providing impedance matching and current driving capability, preventing signal attenuation and noise interference, especially effective when transmitting over long distances or driving large loads.
