摘要

In this letter, the capacitance characteristics of RF LDMOS transistors with different temperatures and layout structures were studied. In a conventional fishbone structure, the peaks in capacitances decrease with increasing temperature. For the ring structure, two peaks in a capacitance-voltage curve have been observed at high drain voltages due to the additional corner effect. in addition, peaks in gate-to-source/body capacitance decrease and peaks in gate-to-drain capacitance increase with increasing temperature at high drain voltages. By analyzing the effects of temperature on threshold voltage, quasi-saturation current, and drift depletion capacitance, the variations of capacitances with temperature were investigated.
