Abstract
A novel proportional to absolute temperature (PTAT) current converter is presented. Output current gain ratios in excess of 50 are possible without the use of an operational amplifier. Simulation measurements show an output temperature coefficient within 15 ppm/°C of the reference current over the temperature range of -40 to +85°C.
