Abstract:
1. An integrated circuit comprising: (a) a composite transistor including at least a first transistor of a first technology type having a first group of intrinsic properties and a second transistor of a second technology type having a second group of intrinsic properties, at least one of the intrinsic properties of the second group being substantially different than a corresponding intrinsic property of the first group, the second transistor having a first electrode coupled to a supply voltage, a second electrode coupled to a first electrode of the first transistor, and a control electrode coupled to a bias voltage conductor and also coupled to a control electrode and a second electrode of the first transistor; (b) a source of bias current coupled to the bias voltage conductor; and (c) a bias voltage across the composite transistor being produced on the bias voltage conductor to bias a cascode transistor.
