Neste artigo, um amplificador de transimpedância (TIA) de operação de equilíbrio com baixo ruído foi implementado para receptores ópticos em tecnologia SiGe BiCMOS de 130 nm, no qual a densidade de corrente do emissor de compensação ideal e a localização do canto de ruído de alta frequência foram analisadas para aquisição. desempenho de baixo ruído. O Auto-Zero Feedback Loop (AZFL) sem introdução de ruídos desnecessários na entrada do TIA, o dissipador de corrente de cauda com altas simetrias e a operação de equilíbrio TIA com a saída compartilhada do Amplificador Operacional (OpAmp) no AZFL foram projetados para manter a operação balanceada para o TIA. Além disso, cascode e shunt-feedback também foram empregados para expandir a largura de banda e diminuir o ruído referido de entrada. Além disso, foi derivada a fórmula para cálculo do canto de ruído de alta frequência em TIA de Transistor Bipolar de Heterojunção (HBT) com realimentação em shunt. A medição elétrica foi realizada para validar as noções descritas neste trabalho, aparecendo 9.6 pA/√Hz de corrente de ruído referida de entrada Densidade Espectral de Potência (PSD), operação de equilíbrio (VIN1=896mV,VIN2=896mV,VOUT1= 1.978V, VOUT2= 1.979 V), largura de banda de 32 GHz, ganho geral de transimpedância de 68.6 dBΩ, consumo total de energia de 117 mW e área do chip de 484 µm × 486 µm.

Abstract: In this paper, a balance operation Transimpedance Amplifier (TIA) with low-noise has been implemented for optical receivers in 130 nm SiGe BiCMOS Technology, in which the optimal tradeoff emitter current density and the location of high-frequency noise corner were analyzed for acquiring low-noise performance. The Auto-Zero Feedback Loop (AZFL) without introducing unnecessary noises at input of the TIA, the tail current sink with high symmetries and the balance operation TIA with the shared output of Operational Amplifier (OpAmp) in AZFL were designed to keep balanced operation for the TIA. Moreover, cascode and shunt-feedback were also employed to expanding bandwidth and decreasing input referred noise. Besides, the formula for calculating high-frequency noise corner in Heterojunction Bipolar Transistor (HBT) TIA with shunt-feedback was derived. The electrical measurement was performed to validate the notions described in this work, appearing 9.6 pA/√Hz of input referred noise current Power Spectral Density (PSD), balance operation (VIN1=896mV, VIN2=896mV, VOUT1=1.978V, VOUT2=1.979V), bandwidth of 32GHz, overall transimpedance gain of 68.6dBΩ, a total 117mW power consumption and chip area of 484µm × 486µm.
