Abstract: The rapid evolution of sixth-generation (6G) wireless communication systems is driving the exploration of D-band frequencies ranging from 110 GHz to 170 GHz to support ultra-high-speed data transmission, low latency, enhanced spectral efficiency, and massive device connectivity. Operating in this sub-terahertz frequency range enables next-generation applications such as immersive communication, intelligent sensing, autonomous systems, and high-capacity wireless backhaul networks. However, the implementation of receiver front-end circuits at D-band frequencies introduces several critical challenges, including severe device parasitic effects, reduced passive component quality factors, higher propagation and insertion losses, limited gain performance, and complex impedance matching requirements in CMOS technologies. This work presents the design and analysis of a 148 GHz LC Bandpass Filter (BPF) integrated with a Low-Noise Amplifier (LNA) for compact and energy-efficient D-band receiver front-end applications. The proposed architecture is implemented using CMOS technology and designed in the Cadence Virtuoso environment to ensure compatibility with highly integrated wireless transceiver systems. The LC bandpass filter is optimized to achieve a center frequency of 148 GHz with an approximate bandwidth of 19 GHz, enabling efficient channel selectivity and suppression of unwanted out-of-band signals in D-band communication systems. To overcome insertion losses introduced by the filter stage and to improve overall receiver sensitivity, a common-source inductive-degeneration low-noise amplifier is incorporated into the front-end architecture. The inductive-degeneration technique enhances impedance matching, gain stability, and noise performance while maintaining low power consumption suitable for next-generation wireless devices. The integration of the BPF and LNA stages minimizes interconnection losses and supports compact monolithic implementation for high-frequency applications. Simulation and performance analysis demonstrate that the proposed CMOS-compatible BPF-LNA front-end achieves effective frequency selectivity, improved signal amplification, and enhanced receiver sensitivity under D-band operating conditions. The proposed architecture offers a scalable and cost-effective solution for future 6G wireless receivers, millimeter-wave communication systems, short-range ultra-high- capacity links, and sub-terahertz sensing applications.
