Flip-flops:
a) Make a asyncronous MOD 12 flip-flop up counter circuit
b) Make a syncronous MOD 14 flip-flop up counter circuit
c) Each flip-flop has the same propagation delay, which is 10ms. Calculate the maximum clock frequency of the circuit in questions (a) and (b)

Please answer both the questions.

1 a) Design two bits comparators using Verilog description language

Note: Design means RTL code and Testbench covering all possible corner cases)

b)

How many latches will result when the following code is synthesized? Assume B is 4-bits long.

                               always@(state)

                               begin

                                        case(state)

                                      2’b00: B = 5;

                                         2’b01: B = 3;

                                      2’b10: B = 0;

                                        endcase

What is the purpose of a pull-up resistor? Explain when this is needed and the consequences of its omission.

Write a program in Arduino that, when it takes in a voltage range (0 to 5 volts), gives a corresponding servo motor angle with a range from 0 to 180 degrees.

The set of AND and OR gates is a functionally complete set of gates.

a)true

b)false

Assume that you are using a piezoelectric material to build a micro/MEMS actuator beam in order to pick up a red-blood cell (with mass of ~1picogram or 10-12grams). If the dimensions of this actuator beam are length=100µm, width=10μm, and thickness=1μm, what is the minimal voltage you need to apply to this piezoelectric actuator in order to pick up the red-blood cell? Please write down all your assumptions used to estimate the voltage required.

1. Write a code that makes the MSP430 blink the red LED and the green LED at the same time. The two LEDs should be on at the same time and then off at the same time
