Varactor Capacitance Vs Voltage
Junction varactor capacitance from zero-bias capacitance, built-in voltage and supplied junction grading exponent.
Description
Junction varactor capacitance from zero-bias capacitance, built-in voltage and supplied junction grading exponent.
Varactor Capacitance Vs Voltage is a focused tool for the following task. Junction varactor capacitance from zero-bias capacitance, built-in voltage and supplied junction grading exponent. It reports Capacitance Farads from the values you provide rather than inventing measurements, coefficients, or professional judgment that are not part of the input.
When to use Varactor Capacitance Vs Voltage
Use this semiconductor calculation for first-order device, material, fabrication, interconnect, packaging, or reliability estimates when every coefficient and unit convention is known.
- Zero Bias Farads (F)
- Required number in F.
- Reverse Volts (V)
- Required number in V.
- Built In Volts (V)
- Required number in V.
- Grading Exponent

How Varactor Capacitance Vs Voltage works
Junction varactor capacitance from zero-bias capacitance, built-in voltage and supplied junction grading exponent. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.
- Capacitance Farads (F)
- Returned number in F.
Limitations and assumptions
- Material composition, geometry, process history, temperature, electric field, bias, interfaces, parasitics, and fitted parameter ranges can invalidate a compact semiconductor model.
- Zero Bias Farads must be at least 0.
- Reverse Volts must be at least 0.
- Built In Volts must be at least 0.
- Grading Exponent must be at least 0.
- Use finite inputs in the displayed units, preserve source measurements and assumptions, and independently verify consequential decisions.
Alternative or Complementary approaches
Compare the estimate with measured process data, current device documentation, and a higher-fidelity circuit, field, thermal, quantum, or TCAD model when the decision requires it.

Quantify BJT base-width modulation (Early effect) from the reverse-biased collector-base junction: fractionalChange = (sqrt(Vbi+VCB)-sqrt(Vbi))·sqrt(2·εSi/(q·NA)) / Wb, with Vbi=builtInVoltageV>0 V, VCB=collectorBaseVoltageV>=0 V, NA=acceptorDopingPerCm3>0 cm^-3, Wb=baseWidthUm>0 um, εSi=11.7·ε0 F/cm, q=1.602e-19 C. Uses stable sqrt difference; checks total voltage finiteness and depletion-factor overflow. One-sided abrupt-junction approximation neglecting emitter side and non-uniform doping; valid for NA not too low and moderate VCB; result >=0, zero when VCB=0.

Compute the Coulomb-blockade voltage e over twice the total capacitance of an island. Formula: Vb [mV] = 80.108832 / C [fF] (since e/(2·C) with e=1.602176634e-19 C, 1 fF=1e-15 F, converted to mV). Input: C > 0 fF. Output: Vb > 0 mV. Assumes an isolated metallic island at zero temperature and that C is the total capacitance to all surroundings.
