Abstract:
A multiply-and-accumulate (MAC) circuit having a plurality of compute-in-memory bitcells is configured to multiply a plurality of stored weight bits with a plurality of input bits to provide a MAC output voltage. A successive approximation analog-to-digital converter includes a capacitive-digital-to-analog-converter (CDAC) configured to subtract a bias voltage from the MAC output voltage to provide a CDAC output voltage. A comparator compares the CDAC output voltage to a fixed reference voltage.
