Abstract
In an example embodiment, an amplifier having high gain and high slew rate is provided and includes a pair of input transistors to which input voltage is applied, a pair of diode-connected loads coupled to the input transistors, at least one pair of current sources coupled to the diode-connected loads, and a bias control configured to turn off the at least one pair of current sources to enable high slew rate for the amplifier and to turn on the at least one pair of current sources to enable high gain for the amplifier. In specific embodiments, the current sources include transistors, the bias control controls a bias voltage to the current sources, and the bias voltage is driven to the supply voltage (V) to turn off the current sources.
