An example embodiment of an active cascode circuit has a control circuit for control of the gate to source voltage (VGS) of at least one transistor in the active cascode circuit. The embodiment may be configured so that control of the VGS also controls the voltage Vin on the input. Vin may be adjusted without altering the device geometry or changing the drain current. This allows for better control and optimization of available headroom for the input voltage in low voltage designs and also results in higher active cascode circuit bandwidth and/or higher output impedance (Rout) for a given power level. |
