High- and low-pass network circuit with integrated amplitude-phase regulation and control method thereof

Abstract

A high- and low-pass network circuit with integrated amplitude-phase regulation, including a high- and low-pass network phase-shift unit circuit and amplitude modulation unit subcircuits each including an amplitude modulation switch transistor and a resistor connected in parallel. The high- and low-pass network phase-shift unit circuit includes high-pass and low-pass network subcircuits. A first end of the high-pass network subcircuit is connected to a first end of the low-pass network subcircuit through phase modulation switch transistors Mand M. A second end of the high-pass network subcircuit is connected to a second end of the low-pass network subcircuit through phase modulation switch transistors Mand M. Body ends of Mand Mare connected through two amplitude modulation unit subcircuits. Body ends of Mand Mare connected through another two amplitude modulation unit subcircuits. A method for controlling such network circuit is also provided.
