METHODS AND APPARATUS TO PROVIDE SLEW ENHANCEMENT FOR LOW POWER AMPLIFIERS
摘要
<p>Methods and apparatus to provide increased current to a cascode amplifier (12) to maximize slew rate are disclosed. The cascode amplifier has a first input (18) coupled to an input switch and a load circuit for amplifying an input voltage on the first input. A slewing input voltage to the amplifier is detected. Current is increased to the load circuit to increase the slew rate of an output voltage (22).</p>
