This paper presents a novel technique for measuring the electrical characteristics of analogue circuits, based on measuring the temperature at the silicon surface close to the circuit under test. As a detailed example, the paper analyses how the gain of an amplifier can be observed through temperature measurements. Experimental results validate the feasibility of the technique. Simulated result...

This paper presents and experimentally verifies an optimized design procedure for a CMOS low noise operational amplifier. The design procedure focuses on the noise performance, which is the key requirement for low noise operational amplifiers. Based on the noise level and other specifications such as bandwidth, signal swing, slew rate, and power consumption, the device sizes and the biasing con...

Low noise and low Power transimpedance amplifiers (TIA) are essential modules for optical sensor based systems. But low power and low noise TIAs are still a challenge for the scientists despite of rapid advances in complementary metal oxide semiconductor (CMOS) technology. This paper proposes a three-stage nested miller compensated (NMC) based design of low noise low power transimpedance amplif...

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.

This article describes a low noise amplifier which is believed will have transformative impact because of the following characteristics: 1) temperature at physical 25 °C factor 4 lower than typical commercial LNAs; 2) decreases to 4.5 K -40 °C, realizable with solid-state coolers; 3) LNA has an integrated, extremely stable source facilitate measurement system temperature; and 4) powered by dc v...

Long BGO (Bi4Ge3O12) and BSO (Bi4Si3O12) crystals coupled with silicon photodiodes have been used to detect minimumionizing particles(MIP). With a low noise amplifier customized for this purpose, the crystals can detect MIPs with an excellent signalto-noise ratio. The nuclear counter effect is also clearly observed and measured. Effect of full and partial wrapping of a reflector around the crys...
