What is the role of the integrator in a sigma-delta modulator, and how can it be implemented using a transconductance amplifier?

The model 2701A converts a voltage signal applied to the input, into a high-resolution output current whose value is directly proportional to the input signal ... The NE5517 contains two current-controlled transconductance amplifiers, each with a differential input and push-pull output. The. operational transconductance amplifier OTA. Thus, it is expected to show the following attractive characteristics: high bandwidth, large dynamic range and ... Mar 14, 2006 ... Op-amps that are designed to provide transconductance should provide very high output impedance and hence provide very good isolation. The ... The curves do not cross at zero input-voltage difference due to mismatch between Q1 and Q2. The differential transconductance amplifier, like many other ... Aug 17, 2022 ... An OTA is a direct-coupled differential voltage-controlled current source (DVCCS) with high output impedance. The Model 8200/8210 Transconductance Amplifiers are precision, high stability, high accuracy instruments which produce an output current which is directly ...
