An improved small-signal model for SiGe HBTs

International Journal of Electronics, 2011
Accurate equivalent-circuit modelling is a prerequisite for the circuit design. In this article, an improved small-signal equivalent-circuit model for silicon–germanium heterojunction bipolar transistors (SiGe HBTs) is proposed. The proposed model has taken into account the effects of the base and collector metallisations, and the corresponding ...

Small signal model for low power DSP

1995 IEEE Symposium on Low Power Electronics. Digest of Technical Papers, 2002
We describe a technique which reduces power consumption in pipelined DSP circuits by mapping full precision operations to small precision operations, using adaptive delta modulation to reduce the signal size. The discrete cosine transform example is evaluated considering issues such as power, area, delay, latency, accuracy of the system and the ...

A comparision of small signal homojunction and heterojunction model

ASDAM '98. Conference Proceedings. Second International Conference on Advanced Semiconductor Devices and Microsystems (Cat. No.98EX172), 2002
The N-AlGaAs/p-GaAs heterojunction with dc bias and small ac signal is investigated. It is shown that its complex small signal admittance consists of two contributions; the first one is the minority electron diffusion in quasineutral p-region region and the second one is the process of thermionic emission at the abrupt heterointerface.

Small-Signal Modeling of Resonant Converters

2011
Resonant DC-DC converters play an important role in applications that operate at high-frequencies (HF). Their advantages over those of pulse-width modulated (PWM) DC-DC converters have led to the invention of several topologies over the traditional forms of these converters. Series resonant converter is the subject of study in this thesis. By variation
