Abstract :
An image reject mixer of Hartley type for the digital TV tuner was designed. It consists of highly linear mixers, wide band polyphase filters, and an adder. The precise quadrature phase against process variation is specially focused. The rejection ratio is aimed at 30dB. The chip was fabricated by TSMC 0.25um 1P5M CMOS process.
