Design and operation of high-gain (>1000), low-power (< 75 jtW), ultra low-noise amplifier arrays are presented. The amplifier array is operated in self-biased mode, such that all amplifiers are biased irrespective of threshold mismatches, and operate with low reset noise. The amplifiers are designed for possible incorporation as pixels of hybrid solid-state photon-counting sensor. The cell pit...

A very low voltage 9th order linear phase baseband switched capacitor (SC) filter has been designed to be used as part of a cellular GSM (Global System Mobile) receiver. A Gaussian-to-6dB filter of the order of seven is chosen and a second order function is added to reduce the group delay variations around. The filter uses a fully differential topology to increase the dynamic range and reduce t...

A low-power, high-gain CMOS low noise amplifier (LNA) for use as the first stage of a subsampling receiver is proposed. The performance of +96-dB voltage gain and less than 1-dB Noise Figure (NF) with very low power consumption is reported for the first time and makes it suitable for subsampling mixer with Track and Hold (T/H) circuit. The LNA contains both tuned and inductorless amplifier stag...

A new approach for designing an ultra wideband (UWB) CMOS low noise amplifier (LNA) is presented. The aim of this design is to achieve a low noise figure, reasonable power gain and low power consumption in 3.1-10.6 GHz. Also, the figure of merit (FOM) is significantly improved at 180nm technology compared to the other state-of-the-art designs. Improved &pi;-network and T-network are used to obt...

The sensitivity of communications systems is limited by noise. Noise figure for low noise amplifier (LNA) design is highly relevant for LNA’s prima-facie function for adding as low as noise to be added to the desired signal amplification when simulated for system level configuration for varied frequencies ranges. In this paper the noise figure was analyzed as performance parameter for C-band fo...

Low Noise Amplifier, CMOS, Noise Canceling, Technique. This paper presents a 0.8V, 3.6GHz narrow band CMOS low noise amplifier (LNA). A current-reused technique is employed to increase the gain of LNA. Also, in order to achieve low noise figure, a noise canceling technique is used in the output stage. The high gain LNA was designed and simulated in 0.13 μm CMOS process. A gain of 27 dB at 3.6GH...
