Muthuswamy Bharathwaj Email corrections to mbharat eecs berkeley edu Summer 2006 Version 1 EE100 Summer 2006 Project Waveform Generator Part I Introduction and Op amp Subsections 1 Introduction In this project you will build a square wave triangle wave and sine wave generator This is the first time we are running this project so there will be a lot of growing pains translation we will grade the project very easily In the first part you will just build the op amp subsection of the project square and triangle wave generator This part is worth 80 of your project grade 2 Examining your kit ONCE YOU GET THE KIT PLEASE MAKE SURE YOU HAVE ALL OF THE FOLLOWING COMPONENTS INFORM YOUR TA AND GET ANY MISSING COMPONENTS BEFORE THE END OF YOUR FIRST PROJECT LAB lab 7 in Summer 2006 Use the table below to record if the component is present or missing Component Op284 10k Brown Black Orange 1k Brown Black Red 5k Green Brown Red 20k Red Black Orange 4 3k Yellow Orange Red 39k Orange White Orange 5 5k Green Black Red 12k Brown Red Orange 5k potentiometer 100k potentiometer 10 uF 22 uF 0 1 uF 0 022 uF 2N3904 NTE Quantity 1 5 3 3 1 1 1 1 1 1 1 4 2 2 1 3 1 Missing Capacitors will either be marked with their value or with a code like 223 The code 223 means 22x103 pF 0 022 uF Many thanks to Ferenc Tho and the entire staff the ESG for making this project possible Prof Meyer was instrumental in helping start this project with his paper on the Differential Pair as a Triangle Sine Wave converter Muthuswamy Bharathwaj Email corrections to mbharat eecs berkeley edu Summer 2006 Version 1 3 Op amp subsection schematic In the first part of the project you just build the op amp subsection A schematic capture of the op amp subsection from MultiSim is shown below Figure 1 The op amp sub circuit in MultiSim Many thanks to Ferenc Tho and the entire staff the ESG for making this project possible Prof Meyer was instrumental in helping start this project with his paper on the Differential Pair as a Triangle Sine Wave converter Muthuswamy Bharathwaj Email corrections to mbharat eecs berkeley edu Summer 2006 Version 1 4 Prelab for Part I 1 You should use lecture 14 to understand how this circuit works 2 Build and simulate the circuit above in MultiSim You can use the Oscilloscope from the Instruments Toolbar to view the output Figures 2 and 3 show you how You should start on this BEFORE lab section although you do have 3 hours in lab to work on it Turn in the simulation result to your TA before the end of lab lab 7 in Summer 2006 Figure 2 Oscilloscope connection Figure 3 Oscilloscope output Note your output will depend on the 100k potentiometer resistance Many thanks to Ferenc Tho and the entire staff the ESG for making this project possible Prof Meyer was instrumental in helping start this project with his paper on the Differential Pair as a Triangle Sine Wave converter Muthuswamy Bharathwaj Email corrections to mbharat eecs berkeley edu Summer 2006 Version 1 5 Part I Lab 1 Build the circuit from figure 1 and show your TA the circuit works Change the 100k potentiometer resistance to demonstrate frequency changes 2 Turn in the check off sheet one per group to your TA BEFORE the end of your lab section lab 8 in Summer 2006 There is no take home report 3 Make sure to take your project kit home you will need it in two weeks for finishing the transistor part of the project WE ARE NOT RESPONSIBLE FOR PROJECT KITS LEFT IN LAB Many thanks to Ferenc Tho and the entire staff the ESG for making this project possible Prof Meyer was instrumental in helping start this project with his paper on the Differential Pair as a Triangle Sine Wave converter Muthuswamy Bharathwaj Email corrections to mbharat eecs berkeley edu Summer 2006 Version 1 Part I Checkoff GROUP MEMBERS 1 Components check TA signature 2 Simulation done TA signature 3 Demonstrated working circuit TA signature 4 Briefly 3 sentences explain why changing the potentiometer resistance changes the frequency of the waveforms 5 Briefly 3 sentences explain why the waveforms have a DC offset of 4 5 V Many thanks to Ferenc Tho and the entire staff the ESG for making this project possible Prof Meyer was instrumental in helping start this project with his paper on the Differential Pair as a Triangle Sine Wave converter
