Abstract: A signal conversion circuit, a PLL circuit, a delay control circuit and a phase control circuit for promoting miniaturization and for reducing quantization noise. TSTC does not require a low-pass filter of capacitor Cm with large layout area conventionally required for converting pulse width to voltage, which promotes miniaturization and cost reduction. TSTC 8 generates analog voltage adequate for transition state at boundary where pulse signal transits, which reduces quantization noise, compared with conventional digital PLL circuits.
