Abstract
An apparatus for setting an attenuation of an attenuator includes a control transistor, which includes a drain connected to a gate of a shunt transistor of the attenuator. A channel resistance of the shunt transistor corresponds to a current density of the control transistor, and the channel resistance of the shunt transistor determines the attenuation of the attenuator. The current density of the control transistor is based at least in part on a control voltage input to the apparatus.
