A 12-bit 60 MHz high-performance pipeline ADC is designed in this paper
which consists of sample/hold circuit
1.5-bit/stage conversion circuit applied from 1 to 10 and a 2-bit flash ADC of the last stage. In this design a gate-bootstrapping switch was used to reduce nonlinear
an operational amplifier with a gain-boosting folded cascade input stage and a class AB output stage was used
dynamic latch comparator was used too
meanwhile
optimizing the sampling capacitor
the gain and bandwidth of the operational amplifier in the circuit stage by stage. In a SMIC 40 nm CMOS process
when the input signal frequency was 1.875 MHz and the sampling frequency was 60 MHz
the SNDR was 68.7 dB
the SFDR was 74.6 dB
the ENOB was 11.12 bits
the core area of chip was 0.95 mm
the total dissipation current was 56 mA under the 1.1 V supply voltage.
