A novel high linear sampling switch suitable for low-voltage operation is proposed. It not only eliminates the nonlinearity introduced by the gate-source voltage variation, but also reduces the nonlinearity resulting from the threshold voltage variation which is not solved in the earlier low-voltage sampling switch. This is achieved by adopting a replica(More)
A transconductance amplifier with extended bandwidth, which is a critical block in various applications including amplifiers, filters and DACs, is presented. The presented technique introduces a differential-mode negative capacitance while introduces the common-mode positive capacitance such that it extends the differential-mode bandwidth and compensates(More)
