In most operational amplifier (op amp) circuits, the resistor tolerance and resistor temperature coefficient determine the gain accuracy and gain temperature drift (Figure 1 shows a typical circuit).
Anthony Wesley, an amateur astronomer from Australia, has combined an industrial camera with image sensors to capture high-resolution pictures of earth’s neighboring planets, including Venus, Mars, ...
Trying to troubleshoot a fault or malfunction in many of today’s consumer-electronic devices is a challenge. For nearly all portable products and many non-portable ones, this is due to several reasons ...
In operational amplifier stability, one rule of thumb is to allow 45 degrees of phase margin. Other design guidelines state that 60 degrees is best; still others say that 30 degrees is sufficient.
