In Conventional power converters electromagnetic interference (EMI) emissions comes from the switching of a DC voltage in pulse width modulation (PWM) process. The effective way to reduce EMI in power converter is to use frequency modulation technique which modulates the originally constant switching frequency by following a certain modulation profile (i.e.(More)
The effect of various biasing conditions and temperature on third order two-tone intermodulation distortion characteristics of InGaP/GaAs microwave DHBTs is studied. The experimental results indicated that the variations in the third order nonlinearity characteristic dip are mainly due to changes in the DC current gain of the device at a fixed and(More)
