Carvajal, "Low-voltage super class AB CMOS OTA cells with very high slew rate
and power efficiency", IEEE Journal of.
As mentioned in Section 3.4, the Timer-A is working at the highest allowed frequency (8 MHz), producing quantization errors in the slew rate
measurements of 1.532%, 4.226%, and 7.154% for the slow, medium, and fast configurations, respectively.
It can be noted that the slew rate
, as expected, has a significant impact on the two considered quantities.
Figure 7 shows the peak SNR for various OTA DC gain, bandwidth and slew rate
. Based on these results, OTA needs to have more than 60 dB DC gain, at least 350 MHz closed loop bandwidth and more than 300 V/us slew rate
The new gradient packages, the Vantage MGV and the work-in-progress ZGV, feature gradient strengths of 30 mT/m and 33 mT/m (milliTesla per meter) and slew rates
of 86 mT/m/sec and 200 mT/m/sec (milliTesla per meter per second), respectively.
As with the envelope detector, the output can never go negative, resulting in the loop having a similar tendency towards slew rate
limited behavior when reacting to abrupt decreases in input amplitude.
As crosstalk is proportional to the change in current over time, it can be reduced by limiting the rise and fall times, or slew rate
, of the bus drivers.
With a slew rate
up to 5 m/s and data rates up to 1,000 data/sec, the LB 500 can also determine the actual feed rate, velocity and acceleration profiles.
The input impedance is 50K ohms, polarity is noninverting, and the slew rate
is 60 v/[micro]s.
This meant designing a telescope with a large FOV and a quick slew rate
. UM staff believed the answer would lie in a telescope control system they call the Robotic Optical Transient Search Experiment (ROTSE), to be placed at Los Alamos (N.M.) National Laboratory.
These figures are nothing to complain about but perhaps are not as fast as the advertised slew rate
of 10 [degrees] per second would lead you to believe.
Additionally, the low input-voltage noise of 0.98 nV/?Hz minimizes noise contribution from the amplifier, and the high slew rate
of 2750 V/s enables wide output voltage swings.
