EE 5293 Project #2 A single stage amplifier Objective: Design an amplifier with an active load (You can choose any amplifier from single stage, cascode, or cascade amplifiers) Design Specifications: Technology: Power supply: Voltage gain: Total Current: Output range: AMI 0.6u 5V CMOS Vod=5 V > 40 dB 3V peak-peak Transistor models nMOS: /homecsu-cdk-1.6.0.beta/models/hspice/standalone/ami06N.m Tax=1.41E-8 m U. - 533.6953445 cm/V-S VTT0.7086 V PMOS: /homecsu-cdk-1.6.0.beta/models/hspice/standalone/ami06P.m Tox = 1.41E-8 m U= 202.4540953 cm/V-S VTHO = -0.9179952V k'= Uo. Cox, Cox= xox/ Tox Eox= 3.5E-13 F/cm PROJECT REPORT GUIDELINES The report should be comprehensive, clear and brief. The report must be typed. Maximum pages: 10pages (11 point font, 1&1/2 line spacing). Here is an outline of what the report should contain: 1. Summary of specifications requested and achieved. (please use a table to compare them) 2. Design methodology of your overall approach describing the critical parts of the design. Please be clear and brief. a) Show schematic with W/L values. b) For the hand calculation, assume Vin=0.7V and Vtp=-0.9V b) Calculate the voltage gain and output swing range. 3. Simulation a) DC Analysis (Show the operating points) b) Plot DC transfer characteristic curve (Vou vs. Van). c) Find the output swing from the linear portion of the DC transfer characteristic curve. d) Plot the transient response with proper input to show the peak-peak output voltages. (The input signal magnitude is depending on the gain of your amplifier.) e) Plot the total current supplied by the power supply. 4. Conclusion and Discussion If you failed to meet one or more of the design criteria, explain why. Suggest how your design could be further improved. Comment on any other aspects of the design as you see fit. GRADING The grading for the report will be performed according to the following weighting: Report format (4 contents) Design methodology Simulations 10 points 20 points 60 points Operating Point DC Transfer curve Transient response Voltage gain Total current 10 Output range 3VP-P > 2.5 Vpp > 2Vpp > 1.5VP-P 10 > 40dB > 37dB > 32dB >20dB 10 50uA 40 dB 3V peak-peak Transistor models nMOS: /homecsu-cdk-1.6.0.beta/models/hspice/standalone/ami06N.m Tax=1.41E-8 m U. - 533.6953445 cm/V-S VTT0.7086 V PMOS: /homecsu-cdk-1.6.0.beta/models/hspice/standalone/ami06P.m Tox = 1.41E-8 m U= 202.4540953 cm/V-S VTHO = -0.9179952V k'= Uo.
