CMRR was established in 1983.The ongoing mission of the Center is the advancement of the state-of-the-art in information storage and memory technologies and systems, in partnership with the information technology industries and government agencies. To fulfill this mission, the Center engages in three interrelated activities: basic and applied research; education at the undergraduate, graduate, ...

A new patented balanced input circuit emulates the extremely high common-mode input impedances which give a quality audio transformer its hum and buzz rejecting advantage in real-world audio systems, where driving source impedances are rarely perfectly balanced. Compared to traditional "active balanced" circuits, the new circuit can produce CMRR improvements up to 80 dB but is only slightly mor...

This paper presents the design and development of a CMOS Instrumentation Amplifier for biomedical application. This design manages to achieve 101dB gain, PSRR > 102dB and 91dB CMRR. The final circuit consumes total of 0.318μWatts power at 1.8V supply voltage and possesses die size of 9.6nm area. It also has a full CMOS implementation of offset cancellation circuitry, among the first of its kind...

This paper describes the design of a current mode instrumentation amplifier using second generation current conveyor(CCII). The current mode approach offers several advantages such as high speed, better noise performance and lower power consumption as compared to conventional voltage mode approach. The design is implemented in standard 65 nm CMOS technology. Simulation is done in cadence enviro...

In this work, an ultra-low-voltage (ULV) technique to improve body-driven current mirrors is proposed. The proposed employed the performance of conventional differential-to-single-ended (D2S) converters which at these low voltages suffer from a common-mode rejection ratio (CMRR). addition, aims D2S also under large signal swing and with respect process, voltage temperature (PVT) variations, res...

In this paper we propose a new low-noise low voltage BiCMOS instrumentation amplifier (IA) with high CMRR and exempted from resistance matching. This IA is dedicated to nerve signal recording as a part of implantable prostheses. The IA design and the simulation with the BiCMOS 0.8 μm technology are presented .The gain is programmable by using a network of resistors. The IA features a common-mod...

This paper describes the development of a low-power electrocardiogram (ECG) touch sensor intended for the use with two dry metal electrodes. An equivalent ECG extraction circuit model encountered in a ground-free two-electrode configuration is investigated for an optimal sensor read-out circuit design criteria. From the equivalent circuit model, (1) maximum sensor resolution is derived based on...
