Abstract: There is provided a trimming pattern enabling trimming to be implemented with ease and time required for trimming to be shortened without causing damage to internal elements. The invention provides the trimming pattern for use in trimming of a semiconductor integrated circuit, comprising two pads to which a voltage is applied, a thin line part interconnecting the two pads, and two connecting parts disposed away from each side of the thin line part, and connected to an adjustment circuit and the semiconductor integrated circuit, respectively. With the invention, trimming is executed by a method of turning the adjustment circuit connected to the connecting parts into the ON state by connecting fused metal of the thin line part to the connecting parts. In this case, since the fused metal can be caused to come into contact with the connecting parts nearby with greater ease than fusion cutting of the thin line part, trimming can be implemented with ease and in shorter time.

Abstract: A chopper type comparator includes an input switch circuit which inputs an input voltage and a reference voltage alternately in response to a control signal; and an output terminal which supplies an output voltage, having a level defined based on the difference between the input voltage and the reference voltage. The comparator further a MOS transistor operating in response to a control signal, and a timing control circuit which provide a delay to the control signal to be supplied to the first MOS transistor and the input switch circuit.
