Band-pass filter co-designed with ESD protection using integrated passive device technology

By co-design methodology, an integrated 2.4 GHz band-pass filter using grounded spiral inductors symmetrically at input/output ports for ESD protection is realized in integrated passive device (IPD) technology. With the novel input/output admittance-inverter (J-inverter) and the weakly coupled trans...

Summary:By co-design methodology, an integrated 2.4 GHz band-pass filter using grounded spiral inductors symmetrically at input/output ports for ESD protection is realized in integrated passive device (IPD) technology. With the novel input/output admittance-inverter (J-inverter) and the weakly coupled transformer, the transmission zeros can be introduced to increase the stop band attenuation. Also, the shunt inductor with enough vias in metal crossover is performed to enhance ESD current handling. It provides an effective bi-directional ESD protection to the ground. The experimental results demonstrate an over 8-kV HBM ESD protection can be achieved. The ESD-protected BPF presents an insertion loss of 1.6 dB at 2.4 GHz with only ~ 0.4 dB degradation compared to BPF without ESD protection.
