Designing private voting rules is an important and pressing problem for trustworthy democracy. In this paper, under the framework of differential privacy, we propose a novel famliy randomized based on well-known Condorcet method, focus three classes in family: Laplacian method (CMLAP), exponential (CMEXP), response (CMRR), where λ represents level noise. We prove that all our satisfy absolute m...

This paper proposes a low voltage (±0.55V supply voltage) low power (44.65µW) high common mode rejection ratio (CMRR) differential amplifier (d.a.) with rail to rail input common mode range (ICMR), constant transconductance (gm) and enhanced frequency performance. Its high performance is obtained using a simple negative averaging method so that it cancels out the common mode input signals at th...

An improved analogue front-end for measuring the high state of trapezoidal voltage pulses with transition duration of 3 μs is presented. A new measurement system, composed by a front-end and the state-of-the-art acquisition board NI PXI-5922, has been realized with improved Common Mode Rejection Ratio (CMRR) of more than 87 dB at DC and 3-sigma stability of ±0.65 ppm over 1 day. After highlight...

Limited Common-Mode Rejection Ratio (CMRR) in balanced interfaces often limits dynamic range in real-world audio systems. Conventional differential amplifier input circuits suffer serious CMRR degradation when driven by real system signal sources instead of laboratory generators. An ideal audio transformer, because of its extremely high common-mode impedances, is virtually immune to this degrad...

This paper describes the design of Current Mode Instrumentation Amplifier (CMIA) for ECG signal Acquisition system. The CMIA topology is based on voltage mode operational amplifier (op-amp) power supply current sensing technique. Op amp mismatch and precise current mirrors are two design challenges of this topology. High Common Mode Rejection Ratio (CMRR) and Power Supply Rejection Ratio PSRR i...

This paper presents a chopper instrumentation amplifier for interfacing precision thermistor bridges. For high CMRR and DC gain, the amplifier employs a three-stage current-feedback topology with nested-Miller compensation. By chopping both the input and intermediate stages of the amplifier, a 1 mHz noise corner was achieved at an input-referred noise power spectral density (PSD) of 15 nV/ Hz. ...

A simple method for designing instrumentation fully-differential (FD) circuits based on standard single-ended (SE) operational amplifiers (OAs) is presented. It departs from a SE prototype that verifies the desired differential-mode transfer function, thereby leading to FD versions of the circuit. These circuits have a high common mode rejection ratio (CMRR), independent of component imbalances...

Differential measurements yield signals that are conditioned by differential or fully circuits which output depends on both the differential- and common-mode input voltages. carry desired information but voltages a nuisance their contribution to signal becomes an interference is usually evaluated from ratio between respective gains for voltages, Common-Mode Rejection Ratio (CMRR). Usually, only...
