To improve the performance of analog, RF, and digital integrated circuits, the cutting-edge advanced CMOS technology has been widely utilized. We successfully designed and implemented a high-speed and low-power serial-to-parallel (S2P) converter for 5G applications based on the 28 nm CMOS technology. It can update data easily and quickly using the proposed address allocation method. To verify the performances, an embedded system (NI-FPGA) for fast clock generation on the evaluation board level was also used. The proposed S2P converter circuit shows extremely low power consumption of 28.1 uW at 0.91 V with a core die area of 60 × 60 μm2 and operates successfully over a wide clock frequency range from 5 M to 40 MHz.

Abstract This paper presents a 31 GHz integrated power amplifier (PA) in 28 nm Fully Depleted Silicon-On-Insulator Complementary Metal Oxide Semiconductor (FD-SOI CMOS) technology and targeting SoC implementation for 5 G applications. Fine-grain wide range power control with more than 10 dB tuning range is enabled by body biasing feature while the design improves voltage standing wave ratio (VSWR) robustness, stability and reverse isolation by using optimized 90° hybrid couplers and capacitive neutralization on both stages. Maximum power gain of 32.6 dB, PAEmax of 25.5% and Psat of 17.9 dBm are measured while robustness to industrial temperature range and process spread is demonstrated. Temperature-induced performance variation compensation, as well as amplitude-to-phase modulation (AM-PM) optimization regarding output power back-off, are achieved through body-bias node. This PA exhibits an International Technology Roadmap for Semiconductors figure of merit (ITRS FOM) of 26 925, the highest reported around 30 GHz to authors' knowledge.

This paper presents a 2.5 Gbps 10-lane low-power low voltage differential signaling (LVDS) transceiver for a high-speed serial interface. In the transmitter, a complementary MOS H-bridge output driver with a common mode feedback (CMFB) circuit was used to achieve a stipulated common mode voltage over process, voltage and temperature (PVT) variations. The receiver was composed of a pre-stage common mode voltage shifter and a rail-to-rail comparator. The common mode voltage shifter with an error amplifier shifted the common mode voltage of the input signal to the required range, thereby the following rail-to-rail comparator obtained the maximum transconductance to recover the signal. The chip was fabricated using SMIC 28 nm CMOS technology, and had an area of 1.46 mm2. The measured results showed that the output swing of the transmitter was around 350 mV, with a root-mean-square (RMS) jitter of 3.65 [email protected] Gbps, and the power consumption of each lane was 16.51 mW under a 1.8 V power supply.
