Use this electronics calculation for a first-pass component, converter, signal, motor, or sensor estimate when the stated operating conditions and units match the device data.

High-frequency voltage gain

Required number input.

Reference voltage gain

Required number input.

Convert an equalizer's high-frequency-to-reference voltage gain ratio to decibels; both gains must use the same amplitude convention. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

High-frequency boost (dB)

The resulting high-frequency boost returned as a number.

• Ideal duty-cycle equations omit switch and diode drops, dead time, ripple, discontinuous conduction, magnetic loss, control-loop limits, minimum on-time, startup, and load transients. Use the converter topology and controller datasheet for a realizable design.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Check the result against the current datasheet and worst-case operating corners, then verify the circuit or measurement with simulation and bench testing where failure matters.

• Op-Amp PSRR dB to Linear

  Convert power-supply rejection ratio from voltage-ratio decibels to a linear rejection factor, 10^(PSRR/20). A 80 dB PSRR means a 10,000:1 small-signal voltage rejection at the stated frequency.

• Gain dB To Linear

  Convert an antenna power gain in decibels to a linear power ratio.

• Linear Gain To dB

  Convert a linear antenna power ratio to an equivalent gain in decibels.
