: OTAs are used to create filters where the cutoff frequency is electronically tunable. This is common in music synthesizers and communication gear. gm≈19

The primary difference lies in the nature of the output and the control mechanisms. The primary difference lies in the nature of

R.M. Marston's Op-Amp Circuits Manual highlights several specialized roles for the OTA that are difficult to achieve with standard op-amps: : By varying the IABCcap I sub cap A cap B cap C end-sub

to zero, OTAs function as excellent electronic switches or gated amplifiers.

with an external control voltage, the gain of the signal path can be modulated dynamically.
