Abstract
An amplifier circuit includes a input point, an output point, and an amplifying path from the input point to the output point. The amplifying path includes a first switch and an amplifier in series with the first switch. The first switch includes a first transistor having a first gate, a first source, and a first drain, the first gate coupled to a control point. The first source or drain is coupled to the signal input point and the other is coupled to the amplifier. The amplifier includes a second transistor having a second gate, a second source, and a second drain. The second gate is coupled to the second switch in the signal amplifying path. The second source or drain is coupled to the signal output point. A third transistor may be coupled to the signal output point through the second transistor in a cascade amplifying configuration.
