500-MHz balanced photodetector using a zero-pole-pair-injection composite feedback network transimpedance amplifier for bandwidth enhancement

L.P. Chen, Xiaokang Zhao, Ziyuan Guo, Bingnan An et autres

Conventional transimpedance amplifier based balanced photodetector is always puzzled by the peaking-response issue as extending its bandwidth above 200 MHz. We propose a zero-pole-pair-injection composite-feedback-network transimpedance amplifier to reshape its closed-loop response. The new design improves the -3 dB bandwidth of the …

A 127-to-156GHz 64QAM/256QAM Zero-IF CMOS Transceiver Chipset Achieving 42dB IRR and 17.8dBm Output Power

Ziyuan Guo, Wei Deng, Wei Dong Zheng, Xinyu Jiang et autres

To address the demand for D-band applications requiring massive access with high modulation orders for users, a DC-coupled zero-IF(ZIF) transceiver chipset is proposed in this paper. To enhance the image rejection ratio (IRR), the transceiver adopts a wideband load-impedance robust stack coupler. …

Residue Amplifier Gain Error Duplication and Cancellation for Two-Step Pipelined ADCs

Ziyuan Guo, Sharisse Poff, J. Marchant, Shiuh-Hua Wood Chiang

This article proposes Error Duplication and Cancellation (EDC) to tolerate the residue amplifier (RA) gain error in pipelined ADCs. EDC cancels the gain error of the RA by virtue of duplicating and subtracting the gain error in the analog domain, thus avoiding …

A 104-to-132 GHz 16-way Power Amplifier Using Enhanced Magnetic Coupling Cavity Achieving 21.2 dBm Output Power in 28nm Bulk CMOS

Ziyuan Guo, Wei Deng, Wei Dong Zheng, Haikun Jia et autres

The ultra-wide absolute bandwidth in the sub-THz range enables high data rate communication and high-precision sensing. CMOS technology, particularly in the D-band (110-170GHz), has demonstrated notable potential in these applications [1]–[2]. In D-band transceiver links, high output power amplifiers (PAs) are essential …
