<p>A method of operating an amplifier comprising a plurality polysilicon thin film transistors (27,29,31,33,39,49,53) including a current source transistor (39) and a load transistor (27,31), the method comprising operating the current source transistor (39) and the load transistor (27,31) at a gate to source voltage less than a threshold voltage (as defined) to reduce the drain conductance of said source and load transistors ad thereby to improve amplifier performance parameters which depend on said drain conductance. <IMAGE></p> |
