A system for analog computing, an analog computing system with sub-binary radix weight representation is provided. The analog computing system comprises an input node, a multiplexer (MUX), a digital to analog converter (DAC), a SRAM-based Sub-Binary Multiplier (SSBM), an analog to digital converter (ADC), a switch, an output node and a calibration module. The calibration module is configured to control the analog computing system to switch between a calibration mode and a normal operation mode. Prior to being switched to the normal operation mode, the analog computing system is configured to perform a process to calibrate a weight parameter stored in the SSBM. The ADC comprises a plurality of multipliers associated with a plurality of sub-binary weight radixes. The weight parameter stored in the SSBM and the plurality of sub-binary weight radixes are configured to represent a plurality of weights for the analog computing system.
