"1.3 V supply voltage, high bandwidth, 100 nA minimum amplitude BiCMOS voltage-controlled current source";
Analog Integrated Circuits and Signal Processing, Vol. 98 (2019), No. 1; S. 209 - 219.

A voltage-controlled current source in 0.35 lm BiCMOS technology is presented. A linear relationship between the control
voltage and the output current is achieved by using first generation current conveyors in configuration of simple voltage-tocurrent
converters. The control voltages of the DC and the AC output currents are completely independent of each other.
The current source is intended for the generation of small currents in a sub-microampere range and in a frequency range of
a few hundreds of megahertz. The measured and simulated results confirm that the smallest amplitudes of the generated
currents are down to 100 nA, with a single supply voltage of 1.3 V. The small-signal bandwidth ranges from 15 up to
900 MHz.
