Patent abstract
A signal converter includes a signal converting unit and a compensation unit. The signal converting unit generates intermediate differential signals at intermediate nodes in response to a single-ended signal. The compensation unit generates compensated differential signals at output nodes by minimizing phase and amplitude mismatch errors between the intermediate differential signals. The compensation unit includes a pair of transistors and a pair of capacitors configured in symmetry between the intermediate and output nodes. The signal converter of the present invention may be used to particular advantage in an RF receiver.
