High-frequency SiGe-selective amplifiers with low bandwidth
Represented in the block diagram of the election based amplifier and current amplifier input converter "voltage-current" allows you to control the central processing element pole frequency and quality factor, as in diagnostic mode parameters of analog devices, and in the mode signal processing. A variant of its circuitry implementation bipolar transistors for microelectronic performance. The results of computer simulation in Agilent ADS confirmed that on the basis of simple current amplifier in the traditional process, due to the structural features of the active elements of ongoing basic level of order can be implemented relatively high-Q units of the second order, which are easily integrated into multi-tier band filters.
