WebWithout a DC voltage, spontaneous polarization can happen freely. However, when a DC voltage is externally applied, spontaneous polarization is tied to the direction of the electric field in the dielectric, and independent reversal of spontaneous polarization is inhibited. As a result, the capacitance becomes lower than before applying the bias. WebTo obtain a DC bias voltage of 2.3 volts, the values of R2 and/or R3 must be adjusted to compensate for the effect of base current loading. To increase the DC voltage dropped across R3, lower the value of R2, raise the value of R3 or both. No distortion of the output after adjusting R2 and R3. pcr cooler gold
