Abstract

An analogue testing standard IEEE 1149.4 is mainly targeted for low-frequency testing. The problem studied in this paper is extending the standard also for radio frequency testing. IEEE 1149.4 compatible measurement structures (ABMs) developed in this study extract the information one is measuring from the radio frequency signal and represent the result as a DC voltage level. The ABMs presented in this paper are targeted for power and frequency measurements operating in frequencies from 1 GHz to 2 GHz. The power measurement error caused by temperature, supply voltage and process variations is roughly 2 dB and the frequency measurement error is 0.1 GHz, respectively.
