전원 공급 장치의 접지 단자에서 기생 임피던스의 영향을 줄이기 위해서는 밀리미터파에 사용할 수 있는 디커플링 장치가 필요합니다. 자주 사용되는 디커플링 커패시터는 기생 인덕턴스로 인해 자기 공진 특성을 가지므로 적합하지 않습니다. 무공진 광대역 디커플링을 구현하기 위해 HAPL(High Attenuation Power Line)이 제안되었습니다. HAPL은 특성 임피던스와 동일한 일정한 입력 임피던스를 가지며, 위상 상수 및 단자 임피던스에 영향을 받지 않는 일정한 절연을 갖습니다. 또한 HAPL은 전력선 역할과 디커플링 장치 역할을 동시에 수행하므로 밀리미터파 회로의 면적 감소에 기여합니다. HAPL은 90nm CMOS 공정으로 제작되었습니다. 제안된 구조는 MOS 커패시터와 등가 직렬 저항을 이용하여 병렬 컨덕턴스와 커패시턴스를 증가시켜 특성 임피던스를 줄이면서 높은 감쇠 및 공진 억제를 실현한다. 200μm 길이의 HAPL을 사용하면 Re(S11)는 무선 개인 영역 네트워크 및 레이더 애플리케이션에 사용되는 비면허 대역을 포함하여 0.9GHz~25GHz에서 -50 미만이고 격리는 90dB 이상입니다. 결과적으로, HAPL을 통해 전원 패드와 급전점을 간단히 연결함으로써 광대역 디커플링을 갖춘 전원 네트워크가 구현됩니다. HAPL은 밀리미터파 회로의 간단하고 컴팩트한 설계에 기여할 것으로 기대된다.

Abstract: A decoupling device that can be used for millimeter-waves is required to reduce the effect of the parasitic impedance at the grounded terminal of the power supply. The frequently used decoupling capacitor is not appropriate because it has self-resonance characteristics due to the parasitic inductance. To realize resonance-free wideband decoupling, a high-attenuation power line (HAPL) is proposed. The HAPL has constant input impedance equal to its characteristic impedance, and has constant isolation unaffected by the phase constant and the terminal impedance. Furthermore, the HAPL contributes to the area reduction of the millimeter-wave circuits because it simultaneously acts as a power line and a decoupling device. The HAPL was fabricated with a 90 nm CMOS process. The proposed structure increases parallel conductance and capacitance using an MOS capacitor and its equivalent series resistance, therefore realizing high attenuation and resonance suppression while reducing characteristic impedance. With a 200-µm-long HAPL, Re (S11) was less than -0.9 and isolation was more than 25 dB, from 50 GHz to 90 GHz including unlicensed bands used for wireless personal area network and radar application. As a result, power-supply network with wideband decoupling is realized by simply connecting power-supply pads and feeding point via the HAPL. The HAPL is expected to contribute to the simple and compact design of millimeter-wave circuits.
