Özet

This paper presents design and simulation of a track and hold amplifier(THA) and a temperature independent reference current circuit for high speed analog digital converter in 0.18 μm SiGe BiCMOS process BCS180G of HHNEC. The THAs circuit is based on the switched emitter follower topology. Therewithal, the reference current source circuit consists of a proportional to absolute temperature(PTAT) and complementary to absolute temperature(CTAT) circuits. The reference current source unaffected by temperature is working with an accuracy of %0.4 between -45 degrees C and 120 degrees C. Respectively, the power supply voltage of the designed THAs circuits and temperature independent reference current circuit is 5V and 3.3V. The active layout area of designed circuit is 0.02534mm(2)(132 mu m x 192 mu m), consuming 465mW at 10GS/s sampling rate.
