The Method of Bandwidth Extension of SiGe BiCMOS Microwave Variable-Gain Amplifier Integrated Circuit
2017
unpublished
Preserved Fulltext
The article proposes a method of bandwidth extension of the analog integrated circuit of the variable-gain amplifier (VGA) based on SiGe BiCMOS technology with the rules of 0.18 𝜇m. The designed VGA has a linear (in dB) control characteristic. The authors consider the VGA architecture and present its design outputs. They describe the properties of two modifications of the VGA integrated circuit-with classical correction of the response and with the circuit of the parasitic capacitance
