一种应用于可定位射频标签中的接收强度指示器
A Receiving Signal Strength Inductor Applied in Localization RF Responder
摘要
Abstract
A receiving signal strength inductor(RSSI)applied in localization RF responder is introduced. A new topology of limiting amplifier with insensitivity to temperature and process variations was proposed. Analysis of gain error,noise and frequency responding of the amplifier was presented. In-band gain of limiting amplifier is 12 dB,and the maximum gain error is 0. 4 dB in band. The interferences among the stages of cascade amplifier was investigated and solved. The centre frequency of RSSI is 2 MHz,and the bandwidth corresponding to the gain,1 dB lower than the maximum response, is 1 MHz. The input reference noise is 82 μV, and the detection range is 48 dB. The maximum ratio of signal to noise is 60 dB. The design is taped out by UMC 0. 18 μm CMOS process,and the meas-urements showed the RSSI chip achieved 45 dB input power dynamical range with 1. 1 mA current consuming.关键词
