This paper presents a design of the transimpedance amplifier using 0.35μm CMOS technology. In the proposed transimpedance amplifier, feedback resistor RF of conventional transimpedance amplifier has been replaced by NMOS transistor as an active feedback resistor. This circuit operates at 3.3V power supply voltage and for a photocurrent of 0.5μA.The proposed transimpedance amplifier having low n...

A two stage sub-µW Inverter-based switched-capacitor amplifier-filter is presented which is capable of amplifying both spikes and local field potentials (LFP) signals. Here we employ a switched capacitor technique for frequency tuning and reducing of 1/f noise of two stages. The reduction of power consumption is very necessary for neural recording devices however, in switched capacitor (SC) cir...

This paper describes the design and measured performance of a 1-8GHz power amplifier MMIC fabricated with a 0.15um Gallium Nitride (GaN) process technology. The process features a 100um thick Silicon Carbide (SiC) substrate and compact transistor layouts with individual source grounding vias (ISV). The design utilizes a non-uniform distributed power amplifier (NDPA) topology with a novel trifil...

Background and Objectives: In this paper, a new design strategy was proposed in order to enhance bandwidth and efficiency of power amplifier. Methods: To realize the introduced design strategy, a power amplifier was designed using TSMC CMOS 0.18um technology for operating in the Ka band, i.e. the frequency range of 26.5-40GHz. To design the power amplifier, first a power divider (PD) with a ver...

Simple instrumentation amplifier circuit diagram using opamp. Equation The addition of input buffer stages makes it easy to match (impedance matching) the amplifier with the preceding stage. A single LM324 op amp Ic is a good choice. feedback differential amplifier. The LMH6550 has the an IF amplifier in high-performance communications. • Video Over TwistedSingle End to Differential Converter a...

Low power single-ended operational amplifier with high slow rate in new technologies due to decreasing dimensionality and supply voltage level has attracted many researchers in recent years. These researchers often used auxiliary circuit for increasing the charging and discharging currents of load and compensation capacitances. Nevertheless, many of these methods are not able to improve the pos...

Simulation of phase sensitive amplifier (PSA) of differential phase shift keying (DPSK) data signal in dual pump is presented. The PSA is designed and simulated using OptiSystem software. A dual pump PSA based on cascaded fiber optic parametric amplifier (FOPA) of 80Gbit/s DPSK data signal is investigated in detail on its gain and noise figure. Results show that PSA has higher gain and lower no...
