T {Resistencia de 250K considerando um resistor de largura fixa de 0,35um;
O capacitor do filtro passa baixas possui um valor de 4pF; 
Logo, a frequencia de corte é 150KHz.
O filtro capacitivo na entrada possui uma capacitancia de 590fF. 
E para uma frequencia abaixo de 150K, possui uma impedancia na ordem de M ohm.} -50 -210 0 0 0.2 0.2 {}
