This paper describes the design of a low power, energy-efficient CMOS smart temperature sensor intended for RFID temperature sensing. The BJT-based sensor employs an energyefficient 2nd-order zoomADC, which combines a coarse 5-bit SAR conversion with a fine 10-bit ΔΣ conversion. Moreover, a new integration scheme is proposed that halves the conversion time,(More)
This paper describes an energy-efficient CMOS temperature sensor intended for use in RFID tags. The sensor achieves an inaccuracy of ±0.15°C (3σ) over the military temperature range (-55 to 125°C) and dissipates only 27nJ/conversion: over 20× less than a previous sensor with comparable accuracy and resolution [2]. This energy efficiency is achieved by the(More)
This paper describes a CMOS temperature sensor intended for RFID applications. The sensor achieves an inaccuracy of ±.25°C (3σ) from –40°C to 125°C, while using 7× less energy than state-of-the-art sensors with similar accuracy [1]. Its energy efficiency is achieved by the use of a zoom ADC that combines a coarse SAR conversion with a fine ΔΣ conversion,(More)
This paper describes an all-CMOS temperature sensor intended for RFID applications that achieves both sub-1V operation and high accuracy (±0.4°C) over a wide temperature range (-40 to 125°C). It is also an ultra-low-power design: drawing 700nA from a 0.85V supply. This is achieved by the use of dynamic threshold MOSTs (DTMOSTs) as temperature-sensing(More)
Built-in self-repair (BISR) technique has been widely used to repair embedded random access memories (RAMs). This paper presents a reconfigurable BISR (ReBISR) scheme for repairing RAMs with different sizes and redundancy organizations. An efficient redundancy analysis algorithm is proposed to allocate redundancies of defective RAMs. In the ReBISR, a(More)
