A distributed and adjustable level-shifting network is integrated with cascaded amplifiers, eliminating the need for a direct current (dc) blocking capacitor between the amplifiers. The level-shifting network can be adjusted to compensate for process variations and to balance the crossover frequency response of the cascaded amplifiers.
