A nested DC offset cancellation circuit based on negative feedback technique
Based on the UMC 40 nm CMOS process, a programmable gain amplifier(PGA) with DC offset cancellation circuit(DCOC) is designed. The PGA adopts a closed-loop resistance negative feedback structure and consists of a cascade of two gain units. DCOC circuit is based on the traditional DC negative feedbac...
