Abstract: A differential phase and amplitude detector circuit is presented. Two source follower circuits respectively based on NMOS and PMOS transistors are used to charge and discharge a sampling capacitor asymmetrically to provide a measurement of phase and/or amplitude difference between two signals of a substantially same frequency. The measurement can be made in one cycle, with the charging of the sampling capacitor performed during a first half cycle where a voltage difference between the two signals is positive, and the discharging during a second half cycle where a voltage difference between the two signals is negative. Biasing of the two source follower circuits enable an excess current flow between the two transistors of the two source follower circuits beyond a biasing current of the transistors to charge the sampling capacitor during the first half cycle, and disable the excess current flow between the two transistors during the second half cycle.
