This brief presents a 2.4 GHz receiver front end in the form of architecture of quadrature LNA-Mixer-VCO-filter (QLMVF) cell in 180 nm CMOS with split-transconductance amplifiers (TCAs). Instead of a single stack-current-reusing QLMV scheme, the proposed design employs two separate current reuse stages with a passive mixer to provide better flicker noise and linearity performance. A shunt-inductive input-match single-ended low noise amplifier (LNA) proposed with an improved package parasitic compensation through a simple varactor tuning. The quad-flat-no-leads (QFN) packaged receiver provides a measured maximum conversion gain of 40 dB, a noise figure (NF) of 10 dB, and a third-order input intercept point (IIP3) of −5 dBm with a spurious-free dynamic range (SFDR) of 60 dB. The front end consuming 2.7 mW of power from a 1.8 V supply and occupies an area of 1.5 mm2.

封装感知 QLMVF 接收器前端

本简介以具有分离跨导放大器 (TCA) 的 180 nm CMOS 中正交 LNA 混频器 VCO 滤波器 (QLMVF) 单元架构的形式介绍了 2.4 GHz 接收器前端。所提议的设计采用两个独立的电流重用级和一个无源混频器，而不是单个堆栈电流重用 QLMV 方案，以提供更好的闪烁噪声和线性性能。一种并联电感式输入匹配单端低噪声放大器 (LNA)，通过简单的变容二极管调谐改进了封装寄生补偿。四方扁平无引线 (QFN) 封装接收器提供 40 dB 的测得最大转换增益、10 dB 的噪声系数 (NF) 和 -5 dBm 的三阶输入截获点 (IIP3) 以及60 dB 的无杂散动态范围 (SFDR)。前端消耗 2.7 mW 的功率，来自 1.
