Title: D/a converter device
Inventor: TANI YASUNORI
IPC: H03H19/00
Filed: 1994-07-11
Abstract: PURPOSE:To effectively attenuate high frequency component included in a digital signal by outputting a signal which is average-moved with respect to the digital input signal of one bit in the constitution of delaying or inverting one of the control signals of a switch. CONSTITUTION:The switch 11 connects with the side of (a), namely connects the one terminal of a capacitor 13 to a reference voltage source when a control signal phi1 is one and connects with a ground side (b) when phi1d is zero. On the other hand, a switch 12 connects with the side of (a) when a control signal phi2 is one and with the ground side (b) when phi2 is zero. Then, the control signal phi1d is delayed by half synchronization of the control signal phi2. Thereby the analog output signal of an integration circuit 16 becomes a code contrary to the output signal of the switch 11. Namely, the analog output signal of the analog integration circuit 16 is obtained by calculating the running mean of the last two values of the digital input signal and inverting a code. Consequently, the frequency characteristic of an output amplitude attenuates largely near Nyquist frequency.
