29.3 A Cryo-CMOS Receiver with 15K Noise Temperature Achieving 9.8dB SNR in 10μs Integration Time for Spin Qubit Readout

Continuous rounds of quantum error correction (QEC) are essential to achieve faulttolerant quantum computers (QCs). In each QEC cycle, thousands of ancilla quantum bits (qubits) must be read out faster than the qubits' decoherence time (<<T2∗~120μs for spin qubits). To address this urgent need, several CMOS receivers operating at...

A Highly Linear Receiver Using Parallel Preselect Filter for 5G Microcell Base Station Applications

By introducing three different techniques, this article, for the first time, presents a wideband highly linear receiver (RX) capable of handling blocking scenarios in fifth-generation (5G) microcell base station applications. First, a parallel preselect filter is introduced to satisfy the base station co-location blocking requirements. Next,...

19.1 A 300MHz-BW, 27-to-38dBm In-Band OIP3 sub-7GHz Receiver for 5G Local Area Base Station Applications

Recently, the so-called sub-6GHz band of the 5G new radio (NR) has been extended to 7.125GHz to address the relentless customer demand for higher data-rate communication. This demands a new design approach for the local area base-station (LA-BS) receivers (RXs) to cover a wide operating frequency range of 0.41 to 7.125GHz. Moreover, for NR...

A Highly Selective Receiver With Programmable Zeros and Second-Order TIA

This article presents a wideband blocker tolerant receiver (RX) for fifth-generation (5G) user equipment applications. Two programmable zeros around the channel bandwidth are introduced to sufficiently suppress the close-in blockers of 5G applications. Since the effect of zeros gradually diminishes at larger out-of-band offset frequencies, an...

A 0.5-3GHz Receiver with a Parallel Preselect Filter Achieving 120dB/dec Channel Selectivity and +28dBm Out-of-Band IIP3

Recent sub-6GHz receivers (RXs) attempted to realize RF channel selection at the RX input for suppressing large close-in blockers. Although mixer-first RXs can achieve sharp RF filtering and good out-of-band (OOB) linearity, they suffer from large noise figure (NF) and high LO leakage [1] [2]. Alternatively, [3]–[5] exploited an N-path notch...

6.5 A 3dB-NF 160MHz-RF-BW Blocker-Tolerant Receiver with Third-Order Filtering for 5G NR Applications

The introduction of the fifth-generation (5G) New Radio (NR) standard has imposed several challenges in the design of sub-6GHz receivers (RX). Firstly, the maximum channel bandwidth(2BW) increases to 100MHz, while a -15dBm continuous-wave (CW) blocker can be located only \Delta f=85MHz away from the desired band edge. Such a small \Delta f/BW...
