This paper proposes a module of a high gain and high swing 2-stage amplifier. It is suitable for building a general operational amplifier in a modular fashion with various optional performances. The proposed module alone offers opened-loop voltage gain up to 124 dB and GBW of 10 MHz without loading conditions. To assemble a 124 dB voltage gain operational amplifier with load driving capacity of...

This paper presents an overview of DelSi, a MATLAB toolbox developed for the design and simulation of delta–sigma modulators. The DelSi toolbox can synthesize a stable noise-transfer function for complex network structures. The modelling tool consists of two crc programs, sdMod.c, a single stage delta–sigma modulator and firfilt.c, a decimating FIR filter. Cascaded modulators can be constructed...

A 70-GHz broadband amplifier is realized in a 0.13-μm CMOS technology. By using five cascaded commonsource stages with the proposed asymmetric transformer peaking technique, the measured bandwidth and gain can reach 70.6 GHz and 10.3 dB respectively under a power consumption (PDC) of 79.5 mW. With miniaturized transformer design, the core area of the circuit is only ~ 0.05 mm. Compared with the...

In this paper we investigate achieving fanout in single electron encoded logic networks. First,we propose an implementation of a charge amplifier and demonstrate its behavior via simulation. Second, we cascade the proposed charge amplifier with an existing design for a linear threshold gate and demonstrate the behavior of the cascaded blocks via simulation. Third, we demonstrate via simulation ...

in this paper a wideband single stage pseudomorphic high electron mobility transistor (PHMET) amplifier has been designed at 5.8 GHz, the input and output matching circuits have a pi form.Noise cancelling principle and sensitivity analysis are performed .Simulation results have been compared with their correspondence in [10] give 2.71 dB improvement in amplifier gain at the same noise figure (N...

The longitudinal space-charge amplifier has been recently proposed by Schneidmiller and Yurkov as an alternative to the free-electron laser instability for the generation of intense broadband radiation pulses [Phys. Rev. ST Accel. Beams 13, 110701 (2010)]. In this Letter, we report on the experimental demonstration of a cascaded longitudinal space-charge amplifier at optical wavelengths. Althou...
