In this paper we propose a variable-gain transimpedance amplifier suitable for low-power applications. Its noise, bandwidth and input impedance performance are similar to a more conventional regulated-cascode common-gate transimpedance with resistive load, with the same power consumption and gain performance. The proposed amplifier has, however, variable gain, which can be easily changed by setting...
An overall increase in power demand together with the liberalization of the power markets and the integration of high capacity unpredictable renewable resources (e.g. wind power) pose a challenge to transmission networks. Network operators have to guarantee a stable and efficient operating of the grid. A way to improve the stability and efficiency of the existing network - aside from expensive reconstruction...
This paper describes a new topology and implementation of a 10 Gbps voltage mode output driver designed for high speed data transfer applications. Using a positive feedback technique, the low power driver achieves the proper internal chip impedance required for matching the line impedance. As a result, return loss is minimized and good signal integrity is achieved. The driver, which consists of a...
This paper describes an implementation of a beam former monolithic microwave integrated circuit (MMIC) for the SKA demonstrator project known as EMBRACE using the SG25H1 silicon germanium process of IHP microelectronics. This process is qualified as a high-performance technology with npn-HBTs up to ft/fmax = 180/220 GHz.
Active power and passive filters (APF and PF) are the traditional ways of compensating for harmonics. However, both of the two ways have some disadvantages, namely resonance and tuning problems in passive filters (PF), and capacity, initial and running cost in active power filter (APF). Hybrid Active Power Filter (HAPF) has been proposed to overcome the disadvantages of APF and PF. It is a combined...
A novel arbitrary waveform power amplifier based on switch-linear hybrid (SLH) technology is proposed in this paper. The proposed amplifier utilizes a source follower to achieve excellent output waveforms quality while a switch-mode tracking power supply is employed to obtain high system efficiency. The steady and dynamic performances of the proposed amplifier optimized by the low system output impedance...
