This paper presents a new high performance Bulk-Driven current differencing transconductance amplifier (BD-CDTA), a recently reported active element, especially suitable for analog signal processing applications. The proposed BD-CDTA provides high output impedances at port Z and X, excellent input/output current tracking. The proposed BD-CDTA circuit operates at supply voltages of ± 0.6V. PSPICE simulation results using TSMC 0.18 μm CMOS process model are included to verify the expected values.

Operational Transconductance Amplifier (OTA) is one of the most significant building-blocks in integrated continuous-time filters. Here we design Low Power Low Voltage Bulk Driven OTA with a new concept of high-linearity OTA with controllable Transconductance is proposed. The OTA is simulated in a standard TSMC 0.18 mm CMOS process with a 0.6 V supply voltage.
