Abstract
A bipolar programmable logic array for producing a substantially constant current to a common sense line (16) includes a bandgap circuit portion (14) for generating a temperature-dependent reference voltage and a current source (IS) responsive to the temperature-dependent reference voltage for providing a switching current to the common sense line which is substantially constant over a wide range of temperature variations.
