A 1.6 V 10-bit 20 MHz current-mode sample and hold circuit

A current mode sample and hold circuit has been designed to examine if high-precision current processing is possible simultaneously with a circuit to which current mode and switched-current circuits are applied and which operates at high-speed and with low supply voltage. The results are 10-bit accuracy, a 20 MHz clock, and a 2 V supply voltage. Clock feedthrough which degrades the precision of current when it is processed in a switched-current circuit is effectively canceled by the use of the newly developed differential configuration
