Abstract
A cascode-connected amplifier circuit including two transistors cascode-connected to each other, where a first transistor having a grounded emitter or a first field-effect transistor having a grounded source, and (a) a second transistor, having a grounded base, which is cascode-connected to the first transistor or to the first field-effect transistor, or (b) a second field-effect transistor, having a grounded gate, which is cascode-connected to the first transistor or to the first field-effect transistor. The cascode-connected amplifier circuit includes a switching element causing a collector of the first transistor or a drain of the first field-effect transistor to be grounded.
