A new fully differential (FD) low input impedance CMOS current buffer with low voltage, and low power operation is presented. The low input impedance is achieved by remarkable reduction of the input node voltage swing using a novel double feedback scheme. Some advantages of the proposed double feedback scheme over the conventional (either positive or negative) feedback techniques are: lower inp...

We propose and numerically verify a novel scheme of all-optical format conversion from non-return-to-zero (NRZ) to binary phase-shift- keying (BPSK) at 160 Gb/s using cascaded microring resonators (CMRR) on a single silicon chip. The conversion is based on large phase shift and flattened intensity-response characteristics in the CMRR. A continuous-wave light experiences different phase shifts c...

In low voltage low power CMOS systems both the high input offset and noise voltages of MOSFETs and also the moderate gain of op amps limit the accuracy of analog circuits. In this paper we present a new high-accuracy instrumentation amplifier; this circuit topology is the first ever reported "non-autozero" instrumentation amplifier which allows to compensate, beside the input offset and noise v...

This paper analyzes the advantages and limitations of using the floating(or flying-) capacitor technique as a building block with differential input and either differential or single-ended output to implement voltage amplifiers, multiplexers, and coherent amplitude demodulators. Theoretical analysis, supported by experimental results, shows that the fully differential configuration has a better...

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 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...
