Abstract

The making of VLSI design ( Very Large Scale Integrated Scale Integration ) needed byplanning of Analog Design and Layout. Where function of making of Analog Design is to translatethe electric circuit becoming a verilog file which there are information about size of IC (integratedcircuit) tha will be formed to use DSCH. While layout represent pattern form to be used in makingof IC, where pattern form to be made have to pursuant to Analog Design which have been made andpursuant to power amplification value and its efficiency. The making of layout used MICROWINDsoftware. Then its result will in test use program of winspice, so that characteristic of class A amplifiercircuit can be seen graphly.In this research is made analog design and layout for the circuit of amplifier class A, thismatter is caused by this circuit still is often used in audio technology and radio, amplifier circuit ofclass A in the form of IC still seldom in selling marketing, and the last amplifier circuit of class Anot to integrated to require compared to higher level energy dissipation which have integrated.

RANCANG BANGUN ALAT KONTROL BEBAN ELEKTRONIK DIGITAL PADA  PEMBANGKIT LISTRIK TENAGA MIKROHIDRO (PLTMh) OFF-GRIDMachmud EffendyStaf Pengajar Jurusan Teknik Elektro, Fakultas Teknik Universitas Muhammadiyah MalangEmail: machmudeffendy@yahoo.comABSTRACTElectronic load control device (ELC) at the MHP Digital Off-Grid (not connected to the PLN) replaces previous controls are still using analog systems (Machmud, 2008), because analog systems have drawbacks including: difficult to perform the initial setup of the generator voltage stability in the event of changes in consumer loads, so that the percentage error generator voltage and frequency stability is still quite large. In 2010 (Machmud) makes ELC models using Matlab with the PI system that is able to stabilize the voltage of the generator at the second to 8.These results continue the previous research by designing wake ELC using microcontroller system that is equipped with PID control. Series of ELC supporters were also made, among others: the sensor circuit voltage, zero detection circuit, and electronic switch circuit. Voltage sensor circuit that has been made to have the voltage linearity level of 0.997. While the time required to trigger the triac with a maximum of 1000 Ohm load is between 0 to 10 milliseconds.PID system is created using the C language and loaded into the microcontroller IC is able to stabilize the voltage generator in the event of changes in the electrical load. With menggunakann value Kp = 4, Ki = 0:01, the system is able to stabilize the voltage of the generator in the event of changes in the electrical load 100 and 500 Ohm 0hm in seconds to 8 parameters Kp in PID control system is applied to the electronic load control devices MHP does not cause changes significant at keluran controller, so its value can be ignored.keyword: PLTMh, Digital Control
