    摘要: A small signal amplifier with a large signal output boost stage are connected between first and second supply rails. The small signal amplifier receives first and second input signals and provides an output signal at an output node which drives a load. Under small signal conditions, the output signal varies approximately linearly with the difference voltage. However, under large signal conditions, a rail-to-rail large signal output boost stage connected to the output node is arranged to drive the output node close to the first or second supply rail as needed to provide the current demanded by the load. The large signal output boost stage is off in small signal conditions, but comes on rapidly and transfers maximum charge to the load under large signal conditions.

    摘要: A cascode circuit with improved withstand voltage is provided. The cascode circuit includes three or more transistors, such as MOSFET transistors. Each transistor has a control terminal, such as a gate, and two conduction terminals, such as a drain and a source. The conduction terminals are coupled in series between two output terminals, such as where the drain of each transistor is coupled to the source of another transistor. A signal input is provided to the gate for the first transistor. Two or more control voltage sources, such as DC bias voltages, are provided to the gate of the remaining transistors. The DC bias voltages are selected so as to maintain the voltage across each transistor to a level below a breakdown voltage level.
