WebFor the lowest pole use curve T_1; this curve refers to the corner frequency; and for the higher pole use curve T_2. The worst agreement is for τ 1 = τ 2. In this case τ ^ 1 = 2 τ 1 and the corner frequency is a factor of 2 too small. The higher pole is a factor of 2 too high (its time constant is half of the real value).

In turn, this means that the product of the frequency and the gain is constant, hence the name gain-bandwidth product. Naturally, the GBW is also the frequency at which the amplifier's gain drops to unity. crystal skiing washington

WebThe first 2-pole section starts with –180° (=180° modulo 360°) due to amplifier phase inversion at low frequencies, increasing to –360° (=0° modulo 360°) at high frequencies. The second section adds another phase inversion starting at –540° (=180° modulo 360°), and the phase increases to –720° (=0° modulo 360°) at high frequencies. http://tera.yonsei.ac.kr/class/2016_1_2/lecture/Lect%209%20Equalizers.pdf WebThe two poles present a stability problem when the high-frequency pole occurs at a frequency where the magnitude of the loop gain is greater than 0 dB. When R o and C are small, the parasitic pole occurs at a frequency higher than the crossover frequency, and the amplifier is stable. crystal skiing holidays 2023
