Abstract

"CIRCUITO DE SAìDA FLUTUANTE BALANCEADO MELHORADO". Um estágio de saída flutuante balanceado mantém controle da corrente de saída de modo comum em ambas as pernas de saída, mesmo quando a voltagem diferencial de saída estiver em corte. O circuito inclui um par de seções do amplificador de transcondutância (gm1) para fornecer um par de correntes de saída em resposta à voltagem de entrada (Vin) ; uma seção intermediária (2-5) conectada de maneira a gerar uma voltagem diferencial de saída intermediária (V1, V2) em duas saídas da seção intermediária, em resposta ao par de voltagens de saída do primeiro amplificador de transcondutância; uma seção de saída (R5-R8) para gerar a voltagem diferencial de saída (vout+, Vout-) em resposta ao par de voltagem gerada pela seção intermediária; uma configuração de laço de realimentação diferencial (R3, R4) conectada em torno do primeiro amplificador de transcondutância e da seção intermediária de maneira a fornecer um laço de realimentação negativa diferencial em resposta à voltagem diferencial de saída intermediária gerada pela seção intermediária; e um laço de realimentação de modo comum que compreende uma segunda seção de amplificador de transcondutância (gm2) conectada em torno da seção intermediária, de maneira a incorporar respectivamente um par de correntes de saída substancialmente equilibradas às correntes de saída do primeiro amplificador de transcondutância em resposta à corrente de modo comum.
