Title:
The dynamic switch driver for the programmable gain amplifier of low distortion
Document Type and Number:
Japanese Patent JP6175100
Kind Code:
B2
Abstract:
A reconfigurable network arrangement of resistors and switches is constructed so that it can be coupled to one or more operational amplifiers and selectively programmed so as to set the gain of the resulting amplifier. The configuration of the network arrangement of resistors and switches to include resistors that can be connected in the feedback path in series and in parallel with each other is such as to provide a wider selection of gain settings, without the need to increase the physical area of the switches on a integrated circuit arrangement.
