.. expensive, the biquad circuit of Figure 1 may be a cost-competitive solution. Many filter applications require higher supply voltages, bipolar operation, or both, so the single 5 V supply associated with most switched-capacitor ...
.. are present, it returns the circuit to standby mode by de-asserting the Hold line. The circuit draws less than 2 uA of supply current while in standby mode, and approximately 40 uA when active. The combined battery monitor and ...
.. colleague asked for the measured jitter number on a single-supply comparator design based on the LM359 IC ( Ref. 1 ). He wanted to know how the jitter performance of the ...
.. short propagation delays (TPD); accurate duty-cycle generation; push-pull, rail-to-rail output; and operation from a supply above 15 V. Figure 1. The schematic and text include several circuit options (current source, transistor ...
.. on. Performance is far better than a FET, and unlike analogue switch ICs, you don't need to mess around with odd power supply voltages. In the off state, distortion is typically less than 0.004% and attenuation in the on state is ...
.. of operation, the discharge of C1 ends when the trigger input level is crossed. This normally happens at one third of the supply rail differential and one third is a long way from zero! But it turns out the 555, despite being such an old ...
.. The cycle repeats at a frequency related to time constants within the bias network. Poor circuit layout or inadequate power-supply decoupling can also cause squegging. These causes are readily addressed, but the solution to the shifting ...
.. isn’t much of an issue. A cool feature of this simple topology is that, unlike many other schemes for digital power supply control, only the regulator’s internal voltage reference matters to regulation accuracy. Precision is ...
.. adapter, this sequel incorporates a ground-referred boost preregulator that can run from a 5-V regulated or unregulated supply rail. The previous linear design has limited power efficiency that actually drops below single-digit ...
