Abstract
Voltage-to-current converters that include two current mirrors are disclosed. In an example voltage-to-current converter each current mirror is a complementary current mirror in that one of its input and output transistors is a P-type transistor and the other one is an N-type transistor. Such voltage-to-current converters may be implemented using bipolar technology, CMOS technology, or a combination of bipolar and CMOS technologies, and may be made sufficiently compact and accurate while operating at sufficiently low voltages and consuming limited power.
Claims15
An electronic component, comprising:
- an amplifier circuit;
- and
- a voltage-to-current converter comprising a first complementary current mirror and a second complementary current mirror coupled to the first complementary current mirror, the voltage-to-current converter configured to:
- generate a current output in response to a voltage input;
- and
- supply, to the amplifier circuit, the current output.
