PMOS Symmetric load differential buffer basic structure

WebWe designed a differential delay cell with symmetric load as the building block of our VCO. The delay cell consists of an NMOS differential pair, an NMOS tail current source, and a PMOS symmetrical load as shown in Fig. 2 (a). The VCO is composed of 4 stages delay cells as shown in Fig. 2 (b). The buffer delay can be defined as: t =REFT ⋅CEFT (1) WebThe delay cells consist of two symmetric load blocks made up from a diode-connected PMOS in parallel with an equally sized PMOS. This load structure demonstrates a symmetric IV characteristic around the DC operating point and is capable of cancelling first-order coupling dynamic supply noise and improving the VCO phase noise [9] [10].
