Circuit designs abound for linear triangle/sawtooth generators, and many are based on the iconic LMC555 CMOS analog timer. But relatively few are voltage controlled, making them tricky to program with ...
In an example DAC application using Actel’s CorePWM IP DirectCore in low-ripple DAC mode (block diagram, Figure 2, main article), PWM output is averaged to a varying dc voltage. At reset, the PWM duty ...
Variable regulated power supplies are handy tools found on well-equipped electronics lab benches. The symmetrical varieties that produce equal voltage outputs of opposite polarity, are even more so.
