A novel linear transconductor using translinear cells is proposed. It consists of a voltage follower, a resistor, and a current follower. SPICE simulations using an 8GHz bipolar transistor-array parameter show that the linear transconductor with a transconductance of 1mS exhibits a linearity error of less than ±0.75% over an input voltage range of ±1V for a supply voltage of ±2.0V. The temperature coefficient of the transconductance is less than 124ppm/℃. The -3-dB frequency of the transconductance is more than 4.5GHz. Applying the linear transconductor as a building block, the design of a bandpass filter with center frequency of 85MHz and Q-factor of 80 is presented.
