A 2.4GHz low noise amplifier has been designed in a standard CMOS 0.35 urn process. The transistor model is Bsim3 for 0.35um process. The amplifier provides a forward gain of 33dB with a noise figure only 0.92dB while drawing 17mw from a 1.5 V supply. Design simulation results are presented in this paper.
A multi-layered perceptron neural network with backpropagation algorithm (MLP/BP) is realized as a waveform equalizer for distorted nonreturn-to-zero (NRZ) data recovery in band-limited channels. Moreover, the proposed approach can tolerate sampling clock skew and channel response variance. According to simulation results, the proposed design can recover… (More)
This paper presents a multi-input multi-output (MIMO) multi-layered perceptron neural network with backpropagation algorithm (MLP/BP). The proposal is a waveform equalizer for distorted nonreturn-to-zero (NRZ) data recovery in band-limited channels with co-channel interference (CCI). From the simulation results, we note that the proposed design can recover… (More)
CMOS LC oscillators using high-Q active inductors with constant-power consumption are presented. The active inductor with one feedback resistor results in a gain-boosting factor to improve the Q-value and the inductance (L) of the active inductor. Based on this high-Q active inductor, a negative resistance LC-tuned oscillator with low constant-power… (More)
In this work, we base on generalized multi-layered perceptron neural networks with backpropagation algorithm (generalized MLP/BP) to construct multi-input multi-output (MIMO) decision feedback equalizers (DFEs). The proposal is used to recover distorted nonreturn-to-zero (NRZ) data in wireline parallel band-limited channels. From the simulations, we note… (More)
Semiconductor nanowires (NWs) have been extensively investigated and discussed in various fields due to their unique physical properties. In this paper, we successfully produce SiGe NWs biosensor by VLSI technology. We propose the dual plasma technology with CF4 plasma pre-treatment and N2 plasma post-treatment for repairs of defects as well as optimization… (More)
Abstraci-A dynamic ADC sampling methodology based on error-tracking loop is proposed in this paper to improve synchronized performance in DSSS baseband transceivers. To maintain the synchronized performance the ADC sampling rate is controlled by error-tracking loop to let clock offset becomes lower. For 1.8MHz clock offset based on 44MHz ADC sampling rate… (More)
