An on-chip sampling oscilloscope with 1ps timing resolution is realized in 90nm CMOS process based on a proposed ramp waveform division scheme for precise signal integrity and power-line integrity measurement. The resolution in time is variable from 1ps to 64ps in 64 steps. A novel on-chip inductance measurement procedure is also proposed.

Fully-depleted silicon-on-insulator (FD-SOI) technology is promising because of its scalability. A 0.5V 100MHz adder and SRAM in FD-SOI has been previously reported [1]. A much faster 0.5V 400MHz FD-SOI processor is presented with power consumption of the 3.5mW. High-speed operation is achieved with zero threshold voltage (V TH ). To suppress leakage, memories accounting for 85% of transistor count are built with a higher V TH of 0.3V. A higher speed of 800MHz is achieved with a 0.9V supply voltage (V DD ) through the V DD -hopping scheme [2], where the higher V DD is applied only when higher performance is needed. It is demonstrated that V DD -hopping is effective even in leakage dominant environments.• 2003 IEEE International Solid-State Circuits Conference 0-7803-7707-9/03/$17.00

This research focuses on the use of RFID (Radio Frequency Identification) systems that are used as personal identification cards in the room access system. This system is intended to maintain the security and privacy of the room from someone who does not have the authority to enter the room. This security system uses a two-tier security system, namely through an RFID identity card and security code. The design and implementation of this system, an electric key work system is evaluated based on the solenoid component and the password used when accessing the room. RFID tags used in this system are in the form of “Mifare RFID Card 13.56 Mhz” cards and store unique codes used as personal identification. This code is read by the RFID reader in validating its authority with Arduino Mega 2560 to regulate the system of electric locks and passwords used to open the door. From the test results, 100% RFID tags can be recognized by the RFID reader, 100% RFID tag and password reading system is successfully used to access the room.
