Abstract
A converter with an additional DC offset includes a switch circuit, a first capacitor, a plurality of additional capacitor cells and an operational amplifier. The converter uses a first additional capacitor cell and a second additional capacitor cell having a capacitor difference with the first additional capacitor to store two charges having different polarity and magnitude with each other, and further generate an inverted DC offset according to a difference between the two charges to compensate a DC offset.
