Large bit-line capacitance is one of the main bottlenecks to the performance of on-chip caches. New sense amplifier techniques need to explicitly address this challenge. This paper describes two sensing techniques to overcome this problem: a current sense amplifier (CSA) and a charge transfer sense amplifier (CTSA) and their implementation based on 90nm CMOS technology. The current sense amplif...

Analysis and simulation are presented of the mismatched load condition for a balanced class-E power amplifier, which is based on 90° hybrids at its input and output. The performances of the 200-Watt balanced class-E amplifier, such as the output power and efficiency, were analyzed and compared to the conventional single-ended class-E power amplifier for the 1:3 VSWR mismatch condition. The simu...

We present a physically-based clutter model for low frequency synthetic aperture radar that includes both distributed scatterers and large-amplitude discrete clutter. The model is used to generate a synthetic forest clutter scene comprised of two components, a background component and a heavy-tailed discrete component. Model parameters are based on characteristics of the scene, such as the rada...

In this paper, we present current amplifier based transimpedance (TIA) for biosensor applications. Proposed design has low-noise, high Transimpedance gain that can be used low measurement The TIA is implemented in order to resolve the fabrication issues related value feedback resistor. design, input block a amplitude amplifier. designed 90 nm complementary metal-oxide semiconductor (CMOS) techn...

An active antenna for transmitter application in S frequency band is designed and analyzed using harmonic balance technique which is based on the nonlinear model of active devices. In this active antenna, the amplifier is integrated with the radiator which is a rectangular patch antenna. This patch antenna is analyzed employing full-wave momentum method. By applying nonlinear model of transisto...

− A piezoelectric accelerometer output voltage with zero shift was induced by the low-frequency response of the charge amplifier. So we designed a virtual amplifier with same input-output characteristic as the charge amplifier, and shock sensitivities of a piezoelectric accelerometer were evaluated by applying the input acceleration to the virtual amplifier. The shock sensitivities were compara...

One of the most common failures or breakdowns that can occur in high-voltage (HV) equipment is due to partial discharges (PDs). This occurs as a result inadequate insulation, aging, harsh environmental effects, manufacturing flaws. PD detection and recognition methods have gained growing attention seen great progress past decades. Radiometric are one investigated approaches their immunity elect...
