Author(s): Suyash Shrivastava, Pydi Ganga Bahubalindruni

Abstract:

This article presents an experimental characterization of a novel 6-bit parallel-to-serial data converter integrated with a Manchester encoder. The system comprises an on-chip digital logic block that generates six mutually nonoverlapping control signals ( $\phi _{0-5}$ ) and three 120° phase-shifted clock signals to drive the switching transistors in the serializer and the …

A 58.9–73.7-GHz Quadrature Dual-Core Class-F₃,₅ Oscillator With Tail-Assisted Implicit Quintupling

A 58.9–73.7-GHz Quadrature Dual-Core Class-F₃,₅ Oscillator With Tail-Assisted Implicit Quintupling 150 150
Author(s): Yevhenii Mormul, Patchara Sawakewang, Sayan Kumar, Chawin Khongprasongsiri, Teerachot Siriburanon, Robert Bogdan Staszewski

Abstract:

We introduce a new class-F3,5 oscillator topology that enables quadrature operation by duplicating a conventional class-F3 oscillator core and electromagnetically coupling the two cores through a pair of additional coils feeding source terminals of the $g_{m}$ transistors. The coupling network enhances the fifth-harmonic component, enabling efficient extraction and quadrature …

A 42-Gb/s PAM-3 Transmitter With a CML Driver and a Dual-Mode Encoder for Process-Variation-Tolerant Middle-Level Generation

A 42-Gb/s PAM-3 Transmitter With a CML Driver and a Dual-Mode Encoder for Process-Variation-Tolerant Middle-Level Generation 150 150
Author(s): Seungwoo Park, Taehwan Kim, Changmin Sim, Seongcheol Kim, Junseob So, Hwaseok Shin, Seon-Been Lee, Chulwoo Kim

Abstract:

This letter presents a 42-Gb/s differential PAM-3 transmitter using a current-mode logic (CML) driver and a dual-mode 3B2T encoder for process-variation-tolerant middle-level (M-level) generation. The encoder selects between two M-level encoding schemes to compensate for load-resistor and driver-current-path mismatches with minimal logic overhead, reducing the standard deviation of …

A Low-Power 10Mbps Squaring-First UWB Receiver Using Frequency Hopping and Two-Tone Modulation

A Low-Power 10Mbps Squaring-First UWB Receiver Using Frequency Hopping and Two-Tone Modulation 150 150
Author(s): Lexie Drackley, Aman Gupta, David D. Wentzloff

Abstract:

This paper presents a low-power 10Mbps squaring-first ultra-wideband (UWB) receiver using frequency hopping code-division multiple-access (FH-CDMA) and two-tone OOK modulation for wireless personal area networks (WPAN). The two-tone receiver architecture preserves IF filtering, improves resilience to narrowband interference, and saves power by eliminating the RF local oscillator. FH is applied …

Abstract:

This letter presents an 802.15.4ab/a/z compatible IR-UWB 2TRX highlighting a full-duplex-based radar, a semisynchronous TX and TRX’s digital baseband. A capacitive tuning technique proposed in the electrical balance duplexer (EBD)-based duplex RF front-end (RF-FE) improves TX-antenna insertion loss by 1.4 dB and the sensitivity of TX–RX …

Abstract:

Mixed-signal CIM (MS-CIM) faces bit-cell nonlinearity, poor linearity at high frequency, and throughput limits. We present a hybrid pipelined current-domain MS-CIM macro featuring bit-cell matched linearization interface (BMLI) and loop-unrolled successive approximation refinement (SAR) ADC fabricated in 28-nm CMOS. A $256{\,}\times {\,}256$ SRAM array with 8-bit inputs, 8-bit weights achieve 10.16-TOPS …

A 12 b 180-MS/s Pipelined-SAR ADC With a Low-Power Calibration-Free RA and Hardware-Efficient SAR Logic

A 12 b 180-MS/s Pipelined-SAR ADC With a Low-Power Calibration-Free RA and Hardware-Efficient SAR Logic 150 150
Author(s): Guo Wei, Rui Zhang, Fule Li, Hanjun Jiang, Zhihua Wang

Abstract:

This letter presents a 12-bit, 180-MS/s pipelined-SAR ADC in 65-nm CMOS. To eliminate the complex interstage gain-error calibration for a fast-response characteristic, a high-gain residue amplifier (RA) featuring a two-stage gain-boosting architecture is proposed. By removing the tail current, the RA significantly alleviates slew-rate and voltage headroom limitations. The …
