A controlled gain transconductor (20) which comprises a transconductance stage (3) having at least two input terminals (I1, I2) and at least two output terminals (O1, O2), an active load (4) connected to the output terminals of the transconductance stage and a control circuit (5) for the active load (4) connected between said output terminals (O1, O2) and the active load (4). Also provided is a circuit portion (10) being a replica of the transconductance stage (3), the active load (4) and the control circuit (5). This replicated portion (10) has an output connected to the control circuit (5) of the transconductor (20) to provide a predetermined voltage value (Vc) required for adjusting the DC gain of the device.

Abstract

A controlled gain transconductor (20) which comprises a transconductance stage (3) having at least two input terminals (I1, I2) and at least two output terminals (O1, O2), an active load (4) connected to the output terminals of the transconductance stage and a control circuit (5) for the active load (4) connected between said output terminals (O1, O2) and the active load (4). Also provided is a circuit portion (10) being a replica of the transconductance stage (3), the active load (4) and the control circuit (5). This replicated portion (10) has an output connected to the control circuit (5) of the transconductor (20) to provide a predetermined voltage value (Vc) required for adjusting the DC gain of the device.

The Electrical and Electronics Engineering category covers resources concerned with applications of electricity, generally those involving current flow through conductors, as in motors and generators. This category also covers the examination of the conduction of electricity through gases or a vacuum as well as through semiconducting materials. Topics include image and signal processing, electromagnetics, electronic components and materials, microwave technology, and microelectronics.
