Abstract :
A monolithic dual-channel peak hold circuit is developed using a semi-custom application specific integrated circuit (ASIC). The circuit is designed specifically for spaceborne instrumentation that requires low-power operation and low-mass packaging. Each independent circuit holds positive pulses and consists of a differential transconductance amplifier followed by a one-way current amplifier. Input gate and output hold functions are enabled by standard transistor-transistor-logic (TTL) or CMOS logic levels. To accommodate a range of applications, quiescent power is adjustable for performance-power tradeoff or can be disabled for single-channel use. Fabricated with dielectrically isolated vertical geometry NPN and PNP transitors, the circuit is inherently radiation-hard and immune to transient upset
