Design a 3-input cmos or-gate using mosfets on the cd4007 chip. make certain that the power dissipation is zero when the output is both logic 1 and logic 0. as an added challenge, design the or gate using the minimum number of cd4007 chips. remember, pins 7 and 14 are committed to ground and vdd, and this limits the placement of these two mosfets in your circuit. add push-button switches to the inputs of the or gate so that pushing the button applies a logic "1" to the gate and releasing the button applies a logic "0".
