Abstract
A low voltage linear transconductor is introduced. The circuit is a pseudo differential architecture that operates with ±0.2V supplies and uses 900nA total biasing current. It employs a floating battery technique to achieve low voltage operation. The transconductor has a 1MHz bandwidth. It exhibits a SNR = 72dB, SFDR = 42dB and THD = 0.83% for a 100mVpp 10kHz sinusoidal input signal. Moreover, st ...

A low voltage linear transconductor is introduced. The circuit is a pseudo differential architecture that operates with ±0.2V supplies and uses 900nA total biasing current. It employs a floating battery technique to achieve low voltage operation. The transconductor has a 1MHz bandwidth. It exhibits a SNR = 72dB, SFDR = 42dB and THD = 0.83% for a 100mVpp 10kHz sinusoidal input signal. Moreover, stability is not affected by the capacitance of the signal source. The circuit has been validated with a prototype chip fabricated in a 130nm CMOS technology. [--]
