    Abstract: In a communication system, a communication terminal device transmits and receives RF signals frequently. Subsequent to an antenna of the communication terminal device, the communication terminal device includes a radio frequency switch (also referred to as transmit/receive (T/R) switch) that switches between two states at a high frequency, where one state is for receiving RF signal and other state for transmitting RF signal. In the exemplary embodiments of the disclosure, a complementary metal-oxide-semiconductor (CMOS) switch is provided, where the CMOS switch is deigned to have a high reliability by coupling a body of a transistor of the CMOS switch to a bias voltage through a switch, where the insertion loss and isolation are improved for the operation of the CMOS switch.

    Abstract: A voltage-to-current converter is disclosed. The voltage to current converter includes a converter circuit having an input node, an amplified signal node and an output. The input node is configured to receive a sinusoidal voltage signal and the output is configured to provide a half-wave current signal. A transistor having a gate, a source, and a drain is coupled to the input node. The input node is coupled to one of the source or the drain. The amplified signal node is coupled to the gate. A process tracking stabilizer is coupled to the transistor at the source or the drain not coupled to the input node. The process tracking stabilizer is configured to generate a control voltage for the transistor. The control voltage is configured to maintain a predetermined non-zero voltage at the input node of the converter circuit during a negative cycle of the sinusoidal voltage signal.
