Abstract—A 15.1 dB gain, 2.1 dB (min.) noise figure lownoise amplifier (LNA) fabricated in 0.13 m CMOS operates across the entire 3.1–10.6 GHz ultrawideband (UWB). Noise figure variation over the band is limited to 0.43 dB. Reactive (transformer) feedback reduces the noise figure, stabilizes the gain, and sets the terminal impedances over the desired bandwidth. It also provides a means of separating ESD protection circuitry from the RF input path. Bias currentreuse limits power consumption of the 0.87 mm2 IC to 9 mW from a 1.2 V supply. Comparable measured results are presented from both packaged and wafer probed test samples. Index Terms—Bias currentreuse, broadband amplifier, lownoise amplifier, monolithic transformer, reactive feedback, ultrawideband. I.

Matching networks are often used at the input of low noise amplifiers to match the input impedance to the source. Generally this matching results in a nonoptimal noise behavior. In addition the matching network itself often generates a significant amount of noise. This paper proposes a wideband LNA, based on doubleloop negative feedback, that has an inherent matched input impedance. It offers the possibility to design and bias the input transisitor for maximum noise performance, and has the potential to increase linearity, without affecting the input impedance. An integrated HF transformer is used in one of the feedback loops and the effects of transformer nonidealities on noise behavior, input impedance and bandwidth are investigated.

In this paper, a lowpower adaptive low noise amplifier (LNA) is presented. The LNA is based on a bipolar cascode topology, uses inductive source degeneration and emitter area scaling to achieve noise and inputimpedance matching simultaneously. The input impedance and the noise factor were simulated as function of the bias collector current and the results show that both are approximately constant over a range of half a decade of bias current, gracefully degrade when the bias current decreases, thereby saving power.

To maximize the bandwidth of dedicated negativefeedback amplifiers by passive frequency compensation, the order of the amplifier needs to be known. Here a method is introduced to determine the order of a circuit with negative feedback. It is shown that the sum of poles in the negativefeedback loop, i.e. the loop poles, can be used to determine the order of the amplifier. These loop poles can be found relatively easily from the circuit diagram and thus the order of the circuit is also relatively easily found.

In this paper, the design of linear amplifiers for current sources with very low, or voltage sources with very high impedance is discussed. In designing negativefeedback amplifiers for these sources, the loopgain is often low as a result of the source impedance, thus making it di#cult to obtain a su#ciently high bandwidth. Here, it is proposed to use CB or CC stages in front of a negativefeedback amplifier. It turns out that the use of these stages does not have to have large detrimental e#ects on noise or distortion properties, while providing a good means to achieve a higher bandwidth. Moreover, the system becomes more robust to source parameter variations. Keywords linear amplifiers, bandwidth optimization, structured electronic design I. Introduction In this paper, the design of linear amplifiers for current sources with a low impedance or voltage sources with a high impedance is discussed. As an example, if a negativefeedback amplifier is to be designed for a very low imp...
