Abstract
An apparatus includes an amplifier to drive a piezo print nozzle in response to a bias current. A bias adjuster includes a plurality of side legs and a plurality of current mirrors. The bias adjuster varies the bias current in the amplifier based on a variable slew rate associated with an input signal of a print command. The bias adjuster is to selectively mitigate power loss and increase slew rate performance of the amplifier.
