Noise coupling path on a fully LTE-compatible receiver circuit chain (Band1, 2110–2170 MHz for downlink) has been analyzed to estimate the victim wires that carry digital noise from RF digital to analogue circuits on the test RF IC chip, three noise-carrying wire groups were extracted out of numerous on-chip wires through systematic measurements and electromagnetic simulation. Then the patterned amorphous...
In-band spurious tones of a LTE-class radio frequency integrated circuit (RFIC) receiver test element group (TEG) chip was studied in order to evaluate the degree of noise suppression by means of soft magnetic thin film. A 2-µm-thick crossed anisotropy multilayered Co-Zr-Nb film was applied onto the passivation layer of TEG chip. The in-band spurious was suppressed by 10 dB while it had no influence...
Intra-electromagnetic noise coupling paths from RF-digital to RF receiver front end can be either of air, wire conduction, Si substrate or package/board. In this paper air and wire conduction coupling paths analysis is discussed. A miniature magnetic near field probe is applied to scan over the test chip to map magnetic near field at LTE band 1(2.1 GHz range). The map is reviewed to extract those...
Single chip integration of RF frontend and digital backend circuits is an obvious solution to accommodate high sensitivity and selectivity of analogue RF chains, and the high speed and large data bandwidth digital processing in an RF IC for the coming wireless communication systems including long-term evolution-advanced (LTE-A) system. This paper firstly emphasizes the necessity to suppress intra...
