Abstract

Ultra wide band Low Noise Darlington Amplifier for High Frequency application is presented. Based on the MOSFET Switching with inductive feedback techniques and inductive peaking method, this technique exits many resonators with high quality factor at different resonance frequencies, Voltage series feedback consist using feedback element inductor, this feedback compensation technique used to sustain stability with respect to larger variation in environments' parameters, applied supply and contains of noise, multi resonant scheme is analyzed and consists high quality factor, high selective in Low Noise Darlington Amplifier, exhibit input matching, low noise and high gain at different frequencies band with relatively low power consumption 2.36pWatt. Achieves -10dB S11 impedance bandwidth achieved from 1GHz to 30GHz, -32dB, S21, -54dB, Minimum noise contain of proposed design is 115pV/√Hz. This Broad LNA Darlington amplifier proposed amplifier used for high frequency application from 1GHz to 30GHz.

用于高频应用的超宽低噪声达林顿放大器
介绍了一种用于高频的超宽带低噪声达林顿放大器。基于感应反馈技术和感应调峰法的MOSFET开关技术,在不同的谐振频率下产生了多个高品质因数的谐振器,电压串联反馈由反馈元件电感组成,这种反馈补偿技术用于在环境参数变化较大、应用电源和含噪声的情况下保持稳定性,分析了多谐振方案,包含高品质因数。低噪声达林顿放大器具有高选择性,在不同频段表现出输入匹配、低噪声和高增益,功耗相对较低(2.36pWatt)。实现-10dB S11阻抗带宽从1GHz到30GHz, -32dB, S21, -54dB,最小噪声包含为115pV/√Hz。这种宽LNA达林顿放大器提出的放大器用于高频应用从1GHz到30GHz。
