Abstract

In recent years, low power consumption has been an important consideration for the design of system since there is a high demand for consumer electronics such as cellphones for a longer battery life. This paper presents the simulation of half adder, half subtractor, full adder, and the full subtractor. The presented circuit contains NAND gates combining the NMOS and PMOS. These CMOS circuitries has the advantage of lower voltage, lower power consumption, and higher energy efficiency. The NMOS and PMOS were bridge together to produce the desired output. This design provides the CMOS half adder, half subtractor, full adder, and full subtractor using the Tanner EDA software tool. The complete CMOS circuit schematic are described in this paper. The design methods and principles are described thereafter. Simulations have been done with the use of the Tanner EDA tool in a CMOS technology standard and response output was verified comparing the obtained waveform along with its truth table. In comparison with conventional logic truth table, T-Spice output simulation matches with theoretical expectations.

Abstract

The Philippines suffered from an inexhaustible number of deadly typhoons, earthquakes, volcano eruptions making it a country prone to natural disasters. Natural causes are inevitable but having a warning device to alert people and prepare them from what’s about to come is essential today. In this paper, the Arduino-based disaster management system is proposed. The device created is a disaster management device that consists of temperature, soil drift, accelerometer, tilt, and rain sensor. A hardware prototype model was developed. It is operated through microcontroller Arduino and implemented using the C language. The effectiveness of the proposed method is verified by experimental studies. If a sensor is activated, it will send data to the selected receiver, which is a mobile phone. Acquired data were provided in this article. Results reveal the effectiveness and efficacy of the proposed system. An expressive future directive has been incorporated at the end of this paper.
