Abstract: An electronic circuit has an amplifier with an amplifying transistor (260) and a cascode transistor (262). A capacitive voltage divider (268) applies a fraction of an RF signal swing from the drain of the cascode transistor (262) to the gate of the cascode transistor (262), the fraction being determined by a ratio between capacitance values. In addition a bias voltage supply circuit (29, 290, 266) is provided. The bias voltage supply circuit is configured to define a relation between an average gate voltage of the cascode transistor (262) and an average drain supply voltage at the drain of the cascode transistor (262). This relation increases the average gate voltage with increasing average drain voltage, and the relation provides a non zero average gate voltage when extrapolated to zero average drain supply voltage.
