Delta sigma switch capacitor filter using curent feed forward |
摘要 |
An electronic circuit having a circuit stage, such as a switched capacitor stage or a 1-bit digital-to-analog converter and switched capacitor filter, that is loaded with a load impedance employs current feedforward to substantially cancel effects of the load impedance. A circuit includes a circuit stage and a load impedance following and connected to the circuit stage. A current feedforward circuit is connected to the load impedance, substantially cancelling the load impedance to improve linearity of the digital-to-analog converter or switched capacitor filter.
