mosfet resistors

Note that stray capacitances on logic signals are in the 1..10pF range, in cables 30pF--1nF or so(*), small signal MOSFET/transistor is a few tens of pF or so, but large power MOSFETs have upto 10nF of gate capacitance - way beyond what a logic signal is designed to handle (perhaps 100pF or so).

(*) which is why raw logic signals can't work at high speeds over most cable runs.
