1. Prepare the presentation on seminer 2.Calculate the resistance values when add the numbers of switches 3. Improve the accuracy of AD converter 7/13 Summarizes the progress of the study and prepare Power point. 7/14 Nothing progress. 7/15 Power point finished. Write report  for class. 7/16 Do a presentation and get advice for re-prepare again. 7/17 Nothing progress

1. Finish VISA application 2. Homework or class question 3. Rearrange the research direction 7/6 Nothing progress. 7/7 Nothing progress 7/8 Tuesday's class work finished 7/9 Writing report about homework. 7/10    

進捗状況201506 1. Learn to use ADC. 6/22 Prepare document about apply visa and translate some document in English. 6/23 Taking classes. 6/24 Visa documents prepared. Learn AD convert information inside PSoC  like judgement. 6/25 Test one AD convert circuit to detect the voltage change.  Set value is from 0-5V and this example succeed. 6/26 Finished two touch switch circuits on broad. The circuit is succeed to … Continue Reading ››

1. Finish the power-point for presentation in next Wednesday. 2. Finished feedback circuit 6/8 Test circuit with the gain smaller than 1 and get a correct  result as calculate result. 6/9 Nothing progress.(Classes ) 6/10 Take part in one presentation ,. Do part of the power-point. 6/11 re-check the simulation and finish power-point. 6/12 Nothing progress. (Classes)  

1.  Finish reports of some classes. 2. Test current amplifier circuit 6/1 Report information search. 6/2 Build differential amplifier circuit and test. check the circuit and found the source ground and signal ground don't put together so the result is not correct. 6/3 Calculate the magnification and compared with the value of voltmeter. Find another noninverting amplifier circuit. 6/4 Finish writing report. 6/5 Try two amplifier circuits but failed. Nothing progress.

進捗状況201505 1. Continue study the detect circuit 5/25 nothing progress 5/26 nothing progress 5/27 Test negative feedback amplifier circuit and got the same result in output terminal. Change another feedback circuit make non-inverting input terminal  as input port but not commit the request of switch output. Still needs find a solution. 5/28 Nothing progress 5/29 Change the feedback circuit to differential amplifier circuit. Reset the circuit and calculate the … Continue Reading ››

Using NJM4580 to amplify the output current. 5/18 nothing progress 5/19 nothing progress 5/20 Try the buffer circuit on NJM4580 , and it worked Learn PSOC from lab research information 5/21 Take seminer and learn PSOC GPIO interrupt 5/22 Do the interrupt experiment circuit and realized it. Continue test the feedback amplifier circuit but the result still wrong.

1.Complete the detection circuit . 2. Test on broad. 5/11 Search information about feedback amplifier circuit on internet. 5/12 Nothing progress 5/13 nothing progress. 5/14 Change an amplifier chip which number is NJM4580 to test the output voltage change.  While the output voltage is larger than the simulation. Using different combination of resistances to test the voltage , just two had been tested. 5/15 Take part in the … Continue Reading ››
