T = numerictype (is_signed, word_length, slope, bias). The dynamic resistance is high (~ 10 6 ohm). Cole notes that fully 91% of all gains over the past century from the 60/40 portfolio have come in just 22 years from 1984-2007. To ensure adequate bias stability, the current flowing through R1 and R2 should be about 10 times. To increase the gain, two or more op-amps are cascaded. To calculate the gain and readnoise using the mode to estimate the data level for each image section: ms> findgain. Due to the gain reduction from feedback, this biasing form is used only when the trade-off for stability is warranted. It tells you directly which bandwidth can be realized for which closed loop gain. I figure I should be fine with a bias point anywhere between about 80% and 95%, so I'm aiming for a bit over 90, assuming it will actually be a bit lower when the voltage drops for the bigger tubes. Assume that your input signal has a DC bias of 3 V, and an AC amplitude of 1 V, and that β=100. Figure 2 illustrates how a typical PID loop works.
