- Stephen Woodward.. conduct and bypass the transistor if the reverse polarity source-drain differential is ever more than a few tenths of a volt. Figure 4 shows the simplest (not very simple) solution I’ve been able to come up with. Figure 4. Two ...Dec 17, 2024
- Stephen Woodward.. is about 18 mA at 80 MHz, which luckily the LT1027 reference is rated to handle. Just. Figure 2. Rail booster and 5.000 volt precision voltage reference. The 16x preaccumulator U2 allows use of microcontroller onboard counter-timer ...Oct 28, 2024
- Stephen Woodward.. circuits. Figure 2 is one practical possibility. Figure 2. A practical source for V+ and V- set R1 and R2 = 200k for ∆ = 1 volt. The Figure 2 circuit was originally described in “Efficient digitally regulated bipolar voltage rail ...Sep 23, 2024
- Stephen Woodward.. perfect supply regulation. It first doubles and then inverts 5 V to generate nominally symmetrical positive and negative 10-volt rails which can each handily supply several milliamps. The complete converter consists of two inexpensive generic ...May 23, 2024
- Steven Hendrix.. transition. Instead, transistors Q610 and Q611 are simple source-followers. As the gate voltage rises more than about a volt above the present value of net VeeDrive shown in Figure 1 at the source terminals of Q610 and Q611, Q611 turns ...Feb 14, 2024
- Stephen Woodward.. op-amp outputs “live” and below zero volts is a job where a few milliamps and volts (or even fractions of one volt) of regulated negative rail can be key to achieving accurate analog performance. The need for voltage regulation ...Feb 9, 2024
- Stephen Woodward.. Figure 1. Adjustable current sink with good precision and other desirable characteristics. To start with, a 2.5-volt voltage reference is produced by an inexpensive shunt regulator chip. The long-used and widely available (and ...Oct 19, 2023
- Jim Williams.. C temperature coefficient. A1 servo controls A2 FET switched current sink via clock synchronized flip-flop to maintain zero volt summing junction (Σ). Loop repetition frequency directly conforms to input voltage. In charge pump ...Aug 29, 2023
- Stephen Woodward.. it relies on electromechanical relays for switching, the archaic technology being attractive because this SD has a 300-volt full scale output. There are of course ways to implement solid state (i.e., fast) switching solutions that can ...Jul 6, 2023
- Stephen Woodward.. Figure 2 The SDD with 5V asynchronous serial data, similar to a µC UART output. Figure 2 illustrates an SDD for 5-volt asynchronous serial data of the sort a µC UART might output, and Figure 3 is its timing diagram. ...Jun 29, 2023
