LIC-Variable transconductance technique"

The variable transconductance technique is used to

• Increase output impedance
• Decrease output impedance
• Increase gain
• Decrease gain

The variable transconductance amplifier is also known as

• VTA amplifier
• CT amplifier
• VC amplifier
• VCR amplifier

The gain of a variable transconductance amplifier is controlled by

• Feedback resistance
• Feedback capacitance
• Input resistance
• Input capacitance

The transconductance of the input transistor in a VTA depends on

• Input voltage
• Output voltage
• Feedback resistance
• Feedback capacitance

In a VTA, the output current is proportional to

• Input voltage and transconductance
• Output voltage and transconductance
• Input voltage and feedback voltage
• Feedback voltage and transconductance
