a Individual transfer characteristics showing the underlying p-type (red) and n-type (blue) behavior for varied back-bias voltages VBB. b When the BB-RFET operates in n-configuration, the output signal VOUT (orange) is delayed by 205.1°. c When the BB-RFET is steered to p-configuration, the circuit is in the follower mode so that the output signal is equal to the input signal in frequency and phase except for some delay of 21.5°. This is a 183.6° phase shift compared to the mode in b.
