“…The other is to protect the inner circuits from breaking at high RF input power. The basic topology of a voltage regulator is shown in Figure 8 [19,20]. It consists of an OTA (operational transconductance amplifier), tow regulation resistances and a voltage reference to generate a regulated voltage using an input voltage reference auto generated Vref.…”

“…The operational amplifier (OPA) used instead OTA shown in Figure 9 compares the voltage reference Vref with the feedback signal from Vreg before producing an error signal to drive the pass transistor M1 for the constant Vreg. The feedback signal is generated by a voltage divider, which contains a four diode connected transistors (M2-M5) used instead resistances R2 and R3 [20,21].…”

<p>In this work a 2 MHz on-off keying (OOK) transmitter/receiver for inductive power and data transmission for biomedical implant system is presented. Inductive link, driven by a Class E power amplifier (PA) is the most PA used to transfer data and power to the internal part of biomedical implant system. Proposed transmitter consists of a digital control oscillator (DCO) and a class E PA which uses OOK modulation to transfer both data and power to a biomedical implant. In proposing OOK transmitter when the transmitter sends binary value “0” the DCO and PA are turned off. With this architecture and 2 MHz carrier wave we have implemented a wireless data and power transfer link which can transmit data with data rate 1Mbps and bit error rate (BER) of 10-5. The efficiency of power transfer is 42% with a 12.7 uH transmitter coil and a 2.4 uH receiver coil and the power delivered to the load is about 104.7 mW. Proposed transmitter is designed for output power 4.1V. OOK receiver consists of an OOK demodulator, powered by rectified and regulated 5V p-p RF signal across the receiver coil. The supply voltage of proposed voltage regulator is 5 V with 9mV/V line regulation of. All circuits proposed in this paper were designed and simulated using Cadence in 0.18 um CMOS process.</p>

“…[4,5]. Many organizations, hospitals, and universities have adopted the RFID technology over other identification technologies such as barcoding, biometric, and other identification technologies due to its low cost, small size, easy maintenance, and the ability to identify objects without requiring light of sight [6,7]. In addition, RFID can be implemented in harsh environments such as dirt and damage, providing the ability of auto-tracking [8].…”

Electronic payment has been considered as one of the most significant and convenient applications of modern electronic services e-University compared to traditional methods that impose time-consuming, human resources, and inefficiency. Different automatic identification technologies have been widely used, such as radio frequency identification (RFID). Extensive research and several applications are focusing on taking the maximum advantage of RFID technology. Data and information security had considered a crucial role when information concerning e-commerce, e-banking, or e-payments, especially due to it required real data to establish accessed illegally. Hence, data originality and security fall a very significant and critical issue in data communication services in recent years. Applications such as e-banking or e-commerce regularly contain sensitive and personal information that should be managed and controlled by authorized persons. Thus, keeping a secure password is important to prevent unauthorized users from illegal access. The password hashing is one of the safety methods and means of preventing attacks. In this article, focuses on proposing an RFID based electronic payment and also provide multi-level security privileges for an academic domain by using RFID technology besides the programmable logic circuit as well the system used C# language in visual studio environment also desktop and web-based application for system working purposes. The proposed system aims to manage student payments in a secure manner and provides the capabilities of getting a bus ticket, copying books, buying food, paying registration fees, and other services. The results have shown the system is secured by using the confirmation code in addition to password encryption.
