How are transconductance amplifiers used in instrumentation amplifiers?

Todiys New 4Pcs for CA3080 CA3080EZ DIP-8 Operational Transconductance Amplifier IC Chip CA3080E: Amazon.com: Industrial & Scientific. Aug 17, 2022 ... An OTA is a direct-coupled differential voltage-controlled current source (DVCCS) with high output impedance. The 52120A is designed for users whose ability to address their calibration workload may be limited by the output current, accuracy and drive capability. The Fluke 5220A Transconductance Amplifier lets you calibrate AC or DC meters and shunts and the current functions of DMM's that measure up to 20 Amps. The ... TA1200 High Frequency Transconductance Amplifier · Current output range：1 mA to 10.5 A · Frequency：DC & 10 Hz to 1 MHz · Short-term stability：0.004%/min @ DC， ... The curves do not cross at zero input-voltage difference due to mismatch between Q1 and Q2. The differential transconductance amplifier, like many other ... Jan 27, 2010 ... The right hand side differential pair transistor collector current is mirrored once off positive rail V+. This gives a current tending to pull ... ... transconductance amplifier. The performance of the proposed circuit is verified with post-layout simulations and worst-case analysis under 135 corners ... The Operational Transconductance Amplifier block provides a behavioral representation of an operational transconductance amplifier. A transconductance amplifier ... Aug 6, 2015 ... Typical use-cases of OTAs are "Voltage Controlled Amplifiers". Lets say you want to control the volume of an audio signal.
