Abstract

PURPOSE:To use only one reference potential generator for a charge transfer type semiconductor device, by generating various reference charges by dummy cells differing in area ratio. CONSTITUTION:Different-area dummy cells 5a, 6a and 7a connecting to reference potential generator 8a generate reference charges (1/2)Q, (5/6)Q, (1/6)Q, etc., and detected charges of sense amplifier 3 corresponding to four kinds of charges outputted by charge transfer type shift register 2 corresponding to a signal of two bits, etc., outputted by multi-level signal generator 1 are supplied to multiplexer 4 to decide on states of 1st and 2nd bits. Therefore, various reference charges are generated by only one reference potential generator without providing generators as many as reference charges, so that while the constitution of the semiconductor device is miniaturized, the integration ratio will be simple.
