In the past few years Silicon Photo-multiplier (SiPM) has emerged as a new detector in various applications due to its promising characteristics for low light detection. However SiPM has certain limitations out of which temperature dependence of gain is an important parameter which limits the application fields to temperature controlled or indoor environment. Change in temperature changes the b...
This paper proposes a CMOS low-power low-voltage microphone preamplifier for a cochlear implant system. The proposed preamplifier using the Flipped Voltage Follower Current Sensing (FVFCS) technique to achieve low voltage, low power consumption. The proposed circuit was designed and simulated using a 0.35 m CMOS process. Simulation results showed that the preamplifier can achieve 22-dB voltage ...
One of the jobs of a circuit designer is to build a measurement system that provides valid input-to-output data as defined by the system requirements over a given frequency range. The four possible elements of a signal path include a gain/signal conditioning cell, an anti-aliasing filter, an analog-to-digital converter (ADC) and a digital processing block. Figure 1 shows this type of system wit...
A low-voltage compatible 120dB gain two-stage amplifier in standard digital CMOS with 3 transistors between VDD and VSS is presented and circuit details are discussed. With the use of precision voltage attenuator, output level monitoring circuits (OLMC) and a digital tuning network, the first stage was tested, achieving ≥76dB DC gains over 2Vpp output swing. With a modest-gain 2nd stage, ≥120dB...
An EEG acquisition system using 0.18μm technology is proposed. EEG input signals are of the range of few micro-voltage. Hence a high gain operational transconductance amplifier with gain of 62.45dB is designed for the acquisition system. The proposed amplifier and multiplexer have been tested for the EEG signals and their performance is reported at operating voltage of 1.8 volts. This design ca...
In sampling mode, S, and S, are on, the voltage across C,,tracks Vi,,, and 4 is configured as a unity-gain amplifier. In transition to the hold mode, S, and S, turn off and C,maintains a unity-gain loop around 4. In this topology, both charge injection of S, and S, and hold-mode droop appear as a common-mode voltage at the inputs of 4, allowing smaller values for C, and C , than in a single-en...
A 1.227 GHz low power single-ended input, differential output low noise amplifier (balun LNA) for GPS is proposed. A two stage structure with current-reused technique is adopted to achieve low power, low noise factor and high voltage gain simultaneously. The LNA is fabricated in 0.18 mm CMOS process, consuming only 2 mA current from a 1.8 V supply. The LNA is measured to exhibit a differential ...
