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".
