对于PANDA探测器的电磁量热计，GSI已经开发了一个名为APFEL（ASIC for Panda Front-end Electronics）的ASIC。该器件针对电容为300 pF、事件速率为350 kHz的大面积雪崩光电二极管（LAAPD）的读出进行了优化。ASIC有两个等效的模拟通道，每个通道由电荷敏感放大器、整形器级和差分输出驱动器组成。为了在宽温度范围内操作ASIC，在芯片上实现可编程电压基准。
For the electromagnetic calorimeter of the PANDA detector a preamplifier ASIC named APFEL (ASIC for Panda Front-end ELectronics) has been developed at GSI. It is optimized for the readout of large area avalanche photodiodes (LAAPDs) with a capacitance of 300 pF and an event rate of 350 kHz. The ASIC has two equivalent analog channels each consisting of a charge sensitive amplifier, a shaper stage and differential output drivers. For operating the ASIC in a wide temperature range programmable voltage references are implemented on chip.
