Abstract
A slew rate booster, switchably enabled selector, or other arrangement may be included in a cascode amplifier to keep the current buffer/common gate transistor and the input/common source transistor saturated as the voltage at the source of the current buffer transistor drops during a transient input voltage spike at the gate of the input transistor. In some instances a higher potential may be supplied to a gate of the current buffer transistor during an initial phase of the settling period than during a second phase of the settling period when a lower potential may be applied. Other techniques may be used in different embodiments. Devices and methods are provided.
