The principle of resistive charge division for position measurement was laid out by Radeka in 1974 [1] but, to date, has not been explored for estimating the longitudinal coordinate for silicon microstrip detectors. To exploit resistive charge division, the impedance of the readout structure must be large relative to the dynamic impedance of the amplifier circuitry. Somewhat counter-intuitively...

This paper presents an all pass voltage mode filter based on recently proposed active building block namely differential voltage current conveyor transconductance amplifier (DVCCTA). The proposed configuration uses single active and two grounded passive components which makes it suitable for IC implementation. Its input impedance is high and output impedance is low, hence suitable for cascading...

Using an electro-absorption duplexer (EAD) we presented a transceiver (TRx) module for dual function of both electrical-to-optical (E/O) and optical-to-electrical (E/O) conversion at 60 GHz band. The EAD chip was fabricated by monolithically integrating both a waveguide photodiode (PD) and an electro-absorption modulator (EAM) in association with traveling wave electrodes. We also investigated ...

The hardware design of tuber electrical resistance tomography (TERT) system is one of the key research problems of TERT data acquisition system. The TERT system can be applied to the tuber growth process monitoring in agriculture, i.e., the TERT data acquisition system can realize the real imaging of tuber plants in soil. In TERT system, the imaging tuber and soil multiphase medium is quite com...

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...

Abstract—The purpose of this paper is to propose a novel generalized single-band transformer for two arbitrary complex load and source impedances and a novel high-power amplifier using this new transformer. By adding two reactive parts at across terminals, the coupled line with flexible electrical length has practical evenand odd-mode characteristic impedances. Thus, the total circuit layout ca...

Low noise amplifier is the front end block of radio-frequency receiver system. Its design required various characteristics such as power gain, noise figure, insertion losses and power consumption. In this paper we have proposed a single stage low noise amplifier design with high gain and low noise using inductive source degeneration topology for frequency range of 3 GHz to 7 GHz and also use th...

Figure 1 shows the equivalent circuit of a transimpedance amplifier and a high-impedance source. IS represents the output current of the source. CS is the sum of the source’s output capacitance and the op amp’s input capacitance. RF, with the help of the op amp, converts IS to a voltage. At low frequencies, the op amp’s inverting input is forced to be at ground potential and IS must flow throug...

The Low Noise Amplifier (LNA) presented in this work offers a gain of 20 dB, a noise figure of 1.6 dB, with an input referred third-order intercept point of –4.5 dBm and a 1 dB compression point of -16 dBm at 5.2 GHz, using 0.35 μm BiCMOS SiGe. It operates on 5 V and requires 10 mA. The output and the input of the amplifier are matched internally to 50 Ω. The amplifier includes an image reject ...

This paper presents an optimization method of wideband filtering power amplifier (PA) with high efficiency. In order to achieve the expected efficiency in wide passband and reduce design difficulty, a high-performance area-based impedance target for computer-aided automatic is proposed, which avoids unexpected degradation caused by conventional target. meanwhile, out-of-band described also prop...
