| 摘要: | This paper presents an automatic gain control (AGC) amplifier with temperature compensation for high speed applications. The proposed AGC consists of a folded Gilbert variable gain amplifier (VGA), a DC offset canceller, inductor-less post amplifiers, a linear open loop peak detector (PD), an integrator, a symmetrical exponential voltage generator, and a compensation block for temperature stability. The novel temperature compensation scheme ensures the AGC stability and accuracy over -20 °C to 200 °C by predicting the integrator biasing voltage based on the crucial blocks duplication technique. The proposed linear open loop PD combined with the linear-in-dB VGA manages error of less than 0.3 dB for the linear-in-dB received signal strength indication (RSSI). The AGC chip is fabricated using a 0.13-？m SiGe BiCMOS technology. Consuming a power of 72 mW from a 1.2 V supply voltage, the fabricated circuit exhibits a voltage gain of 40 dB and a 3-dB bandwidth of 7.5 GHz. With a 215-1 pseudo-random bit sequence at 5-Gb/s, the measured peak-to-peak jitter is less than 40 pspp across the -20 °C to 200 °C temperature range. The low linear-in-dB error and the wide operating temperature range achieving the high speed data input signal indicate the suitability of the proposed techniques for high speed AGC amplifiers. |
