This paper presents a low-power embedded EEPROM in a short-range passive RFID tag. This tag was designed according to ISO/IEC 15693 protocol. An improved structure of array circuit is proposed which can reduce leakage of memory bit cell efficiently. The proposed circuits can reduce maximum to 8μA per bit cell. A new RFID EEPROM timing design and its optimized control circuit are developed. The fabrication...
This paper presents a detailed analysis on the relationship between quality factor (Q) and the amplitude of CMOS LC VCO. It is shown that controlled voltage amplitude is benefit for acquiring a large Q of the oscillator. Low power and phase noise of LC VCO can be optimized by tuning Q of tank. The analysis has been carried out both theoretically and by simulation for the design of a low power and...
