ABSTRACT:
The broad-band integrator uses bipolar transistors with single low-value integration capacitor, that is why it is easy to integrate. A bias circuit, which can be integrated, allows both the gain-bandwidth product (G*B) and the absolute values of the currents in the transistors to be programmed by two external resistors. A plurality of integrators, typically sixteen, can be connected to the same bias circuit thanks to their small power consumption.
