This paper presents two new wireless temperature sensors made with a standard CMOS process exhibiting an on-chip antenna. The realized chips include a 3-stage ring oscillator structure which transforms the silicon substrate temperature variation into a frequency modulation. The first device works at a frequency of about 750 MHz @ 30degC. The signal is transmitted by a small loop antenna structure which is realized by aluminium deposition on the top surface of the chip. The electronic design of… CONTINUE READING
