ANALOG MULTIPLEXER
Document Type and Number:
WIPO Patent Application WO/2007/114265
Kind Code:
A1
Abstract:
An analog multiplexer selects one of input signals inputted to N primary input
terminals (N is an integer of 2 or more) and outputs the selected signal to a primary
output terminal. The analog multiplexer comprises N amplifiers, N switches,
N loads, and a common load. Each of the N amplifiers has a first input terminal
connected to each of the N primary input terminals, a second input terminal electrically
connected to the primary output terminal, and an output terminal. Each of the
N switches has an input terminal connected to the output terminal of each of the
N amplifiers and an output terminal connected to the primary output terminal.
The N loads are connected between the output terminals of the N amplifiers and
a first power supply line, respectively. The common load is connected between
the output terminal of the N switches and a second power supply line.
