Desain Layout 1-Stage ADC Pipeline 80Msps Dengan Mentor Graphics 0,35µm Untuk Aplikasi Kamera Kecepatan Tinggi

Design layout 1-stage pipeline is part of the 8-stage pipeline 80 Msps ADC. Layout 1-stage pipeline consists of 3 units : op-amp, switch capacitor, precision comparator with latch. Pipeline ADC works gradually and requires synchronization of digital output 8 stage by using a unit delay circuit (D-FF). Pipeline ADC requires pulse rate (clock) generator to support its work. Units OP-AMP transconductance CMOS components designed with the correct specification ADC applications with capacitive loads, with a large input impedance and minimize noise. The precision comparator has Vos (offset voltage) approximately equal to 0V. The capacitor switch designs use NMOS switch as a switch for the sampling and multiplying. In the sampling phase and multiplying processes, the ADC requires a clock pulse with a non-intersect mode (lapping). The width of non-overlapping period was adjusted to the time of constance in the sampling process and multiplying. The total number of each pulse period equal to 12.5 ns or equal to the frequency of 80MHz. In the 1-stage layout an additional correction capacitor was required to correct residual voltage. The total area of the layout 1-stage pipeline ADC is 1-bit 200 μm x 98μm

Merancang dan Implementasi Vpn Pptp untuk Koneksi Client Server Aplikasi Keuangan Ifas (Studi Kasus pada Yayasan Teratai Putih Global)

The Teratai Putih Global Foundation is an institution engaged in the field of education which has 9 (nine) school units from Islamic preschool, Islamic Elementary School, Islamic Junior High School, Islamic High School and Vocational Schools spread across Bekasi and Jakarta. The data collection process is mainly related to the administrative and financial processes of students and the recording of school financial cash flows. The foundation and the nine units have school administration system software IFAS (Integrated Finance and Accounting System) in their respective school units, this condition makes it difficult for the foundation to consolidate data and daily reports in real time because they are not connected to each other. VPN (Virtual Private Network) technology allows anyone to be able to access the local network from outside using the internet. The purpose of using a VPN is so that users can access the resources on the server, connect to the database server in real time and get the same rights and settings as physically in the place where the local network is located. With the NDLC (Network Development Life Cycle) method, a method for designing and building networks, VPN connections are designed for a client-server topology and successfully implemented for the IFAS program to run well and smoothly
