This paper proposes a third-order bandpass filter using low temperature co-fired ceramic (LTCC) technology. The filter employs two grounding inductors, connecting the two parallel LC resonators, to provide a transmission zero in the upper stopband. A feedback capacitor between input and output is also used to generate two transmission zeros. With the help of stepped-impedance resonators (SIR's), the...
In this paper, inductors embedded in a mold material are characterized. Due to the low-loss property of the mold material, plated Cu inductors show high quality-factor (Q) performance. This performance is also better than those of similar inductors implemented from our IPD process. The mold material is not only used as a supporting substrate, but also served as package substrate, which allows the...
A small form-factor balanced filter for WiMAX applications is developed using silicon-based IPD technology. The balanced filter (1.2 mm times 2.0 mm times 0.4 mm for flip-chip version, and 1.2 mm times 1.6 mm times 0.25 mm for wire-bonding version) is the smallest device achieving similar electrical response, to the best of our knowledge. The insertion loss at the pass-band is 2.0 dB. The attenuations...
ESD failure limits have been measured in a variety of silicon integrated passive devices using the Human Body Discharge Model. The failure mechanism for these circuits is typically the destructive breakdown of the thin insulator layer in metal-insulator-metal capacitors. The capacitors in this particular technology have a static breakdown of 70 to 100 V. Failure from ESD events for a single capacitor...
