in mosfets, the gm of the transistor will go down with temperature due to carrier mobility decrease. The vgst(Vgs-Vt) or overdrive voltage is inversely related to gm. High Vgst will give better transistor drain current matching. So as temperature changes, the Vgst will change and the matching of the drain current in the devices will change.
